Astonishingly not bad for $100
I have a Kurt DX6 That is my primary vise on my bridgeport but I needed to steal it to use for a setup on my CNC that has Saunders vises that were just too small for what I needed. After the CNC was setup and running I ended up needing to run a job on the bridgeport but had no vise. So I took a chance on this one for $100. You dont get much for $100 these days and I was expecting garbage. I'll start out by saying this is no Kurt... But... its astonishingly not bad. It did arrive with sharp edges like other reviewers said, and I had to file and stone it right out of the box. The screw needed some oil and the whole thing just needed to be cleaned up a little bit. Once that was done I mounted it on the mill and threw up my indicator. Tapped it around and got the vise within .001" X Y and Z. Jaws come together perfect and you can put some weight on the vise handle to clamp something down. Does what it needs to do and does it pretty well. The only thing I dont like is that the mounting slots are about .820" wide, which makes it awkward to mount with 1/2" studs but still doable with some heavy washers. All in all, like I said, astonishingly not bad for $100.

Impressed !!
Unit shipped well oiled. I bought this vise for firearm work.... The jaws are ground smooth and true. They are perfectly square. The jaws also go all the way down to the table. This vice is a great value.

Glad I took a chance!
Really good for the price. Wish I could afford a “Kurt,” but I can’t. And as a hobbyist, I would be overkill. For the price, I could give it five stars, but I took one off due to the need to take it completely apart to clean and file (or sand) down the razor sharp edges. I knew this was needed from watching YouTube reviews. I’m sure this is one of the ways they keep the price down. I used a good test indicator across the machined surfaces and it checked out very well. Vice jaw opening is more than advertised and I the rear jaw can be moved to the back to hold a piece around 12 inches. This is not just a “first impression.” I have used it on my “old but rebuilt” Bridgeport J-head mill, and am pleased with its performance. My only complaint is the sloppy handle. The socket end fits fine. It is the pivot part that is sloppy. I’m sure all the lesser priced vise manufacturers buy the same sloppy vice handle for a couple of dollars. I will either make a new one, or buy one of the combo speed handles. Don’t let that deter you. The handle is functional, just not the quality I want, but the vice is still a great value.

High quality for the money
I expected this to be a crappy Chinese vise I used to have 15 years ago. I used a Kurt DX6 before so I’m comparing this $120 to a $700+ vise. It’s not a Kurt, but surprisingly…it’s the same in regards to functionality. It holds a part with good accuracy. Parts do not shift at all with heavy clamping from one edge. Not even 0.0001”. Yes. Tenths gauge is rock solid when I put half my body weight on the vise screw. Just like a Kurt DX6. Make sure to wear gloves and spend an hour deburring all the knife edges it has. They will split your hand open easily. Moving the jaws isn’t as smooth. A Kurt glides like glass. This vise felt stiff. Lots of cleaning and using proper way oil helped. Just be glad there’s a good option like this if you’re just starting out. Great for a home gamer. I’m using it on my CNC. If you want a dual or triple vise setup on your table at home this starts to make a lot more sense. $1500 vs $250 is kind of a wild difference. Just make sure your table is big enough if you get the 6”. These vises aren’t small.

Excellent for the price. Better with some simple mods.
The 6" vise is surprisingly good for $100. It's definitely no Kurt DX6, but it's almost 1/7th the cost. A couple things to note though: The bottom edges and jaws have some very sharp edges. I hit all bottom edges with a quick file to get things a little safer. I'd recommend stoning the bottom too, if you have one, after the filing. The jaws are also very sharp, and got a similar treatment. A very important observation, this vise is not compatible with standard 6" jaws that would work with Kurt vises. The attachment bolts are M8 instead of 1/2" and are positioned too low to use other jaws without modifying the other jaws. I needed to make some custom soft jaws for this vice, the Kurt ones just will not fit. Finally, the hex for the handle on the leadscrew is not a standard 3/4", rather it appears to be larger, more like 20mm. This doesn't matter too much except my other vise handles and speed wrenches won't fit. I ended up removing the leadscrew, champing it in vise jaws I have for machining hex bar stock, and brought the size down to a proper 3/4" so all of my other wrenches fit. I'm not sure if all of these are like this or just the one I received. Overall, I'm very happy with this vise. Very surprised. I'll update this if I see any issues with longevity.

Very Nice Vise
I did a lot of research and looking around before I settled on this particular vise. I tend to put a lot of credit into the reviews that others write about their experience with products that I am interested in. I start with the star ratings and the number of reviews a product has received before moving on to the written reviews. True... this vise didn't have as many reviews as I typically like to see but I checked it out none the less. When I first opened the package the first thing that I noticed and thought was kind of odd was the fact that they only put packing material on the top side and and did nothing to protect the all so important bottom of the vise. There was no apparent damage but certainly something they should consider going forward. I will give it a closer inspection to ensure there is no damage and for flatness before i secure it to my mill. Like others have said, this thing is a lot bigger than I expected, but since I have a full size mill that won't be a problem. If you have one of the bench top mills the size and weight of this vise could be an issue for you. The next thing I noticed is what I thought was perhaps a milled test block that had been accidentally left in the jaws. After I attached the handle and started cranking the jaws open to remove the block I realized that the block was the jaw when I saw the seam start to open. I clamped the jaws closed again and the seam vanished. The jaw faces are perfectly (as far as the human eye can see) machined. I have not yet attached it to my mill for a test run but I have no doubt that it will provide my desired outcome. Unless something unexpected and catastrophic happens when I put it in operation, and I seriously doubt that will happen, I would absolutely recommend this product. I am certain that one can find a much more precise vise, but for the home shop and at this price I think this is a very good buy.

Careful: razor sharp edges!
The vise arrived today in a fairly beat-up box. Inside, the vise is shipped upside-down in protective styrofoam. But there was nothing protecting the vise base (at the top, as it's upside-down)! And there's a good inch of air space between that vice bottom surface and the inside top of the box, so I'm guessing that there SHOULD be styrofoam there. Perhaps this was a returned unit, re-shipped. Thankfully, despite the lack of protection of the banged-up box, the base surface seems OK. Just a few nicks that should stone out. While lifting the vice out of the box, I gave myself quite a nasty cut on my left index finger, right across the inside knuckle. After finally staunching the bleeding and getting back to the vice, I found (carefully this time!) that almost all of the top surfaces have razor-sharp edges. Nothing is deburred or filed or chamfered. So beware! I took a good file to all of the edges to knock them down. The vice itself seems really well made (apart from the lack of deburring), heavy and very solid. The mechanism is taught but slides well, with no grittiness. There's no sign of rust, and the paint is applied well. The jaws are 5 1/16 inch wide and it opens to 5 15/16 (not quite 6) inches. The supplied handle is pretty basic, and I'll probably make another myself. The "grade 8" bolts supplied seem OK but I'll probably not trust/use them. And one of the two supplied washers is D-shaped (manufacturing defect). No big deal. I don't know why all vices of this design tend to waste vertical real-estate, when every 1/4 inch of Z travel on a small hobby mill is precious. The base on this could easily be 1/2 inch thinner with no loss of utility. In summary: it's a good solid vice, good value, and there's a good chance that I'll buy another. But I'm knocking off 2 stars because of the poor packaging and my blood loss.

Very nice, required a little fine tuning 👍
Reviewing my new Happybuy 5" Accu Lock Vise. Vise arrived in a sturdy cardboard box partially filled with styrofoam surrounds, box was a little beat up but that's just from the shear weight of the vise and not having a styrofoam top liner (which should be included, that would have prevented all the shifting around in transport). Measurements (which everyone wanted to know) are as follows: 14 3/4" long without handle attached. 7 1/4" wide base flange to flange tips. 4 3/16" tall, 5" jaws, a big 5 7/8" max jaw opening (the ad only claims 5"), heavy 3/4" dia lead screw, 1 9/16" jaw height, 6 1/4" center to center base bolt down holes and a stout 36 pounds total. This is a very nice vise for the money. It arrived pretty clean (no metal shavings) with a very light coating of clear oil, all milled edges are razor sharp, crisp and very flat and smooth, the painted casting areas are nice with only a few sharp jagged spots. The paint job is great with a nice blue-green hammered look. The bag of included hardware is as others say a bit on the cheap side but that's not a big deal to upgrade and replace yourself. I spent about 3 hours cleaning, scraping, filing, sanding and oiling the vise. The entire inside lenght of both ways had some paint overspray on them that kept the jaws from moving easily. The two square cutouts up front had some razor sharp jagged edges that needed to be hand filed down to avoid seriously cutting yourself on. The entire bottom edge is also very sharp which I lightly filed and sanded back to avoid cuts as well. A very light coating of oil was applied to all bear metal surfaces to prevent rusting. I can turn the vise with just my fingers now without having to use the handle, which was impossible before fine tuning it up. I'm a serious diy guy and not a professional machinist so I'm not using this vise on a mill of any kind. I'm adding it to my big floor drill press to drill metals, plastics, woods, etc (I'm not using my drill press as a mill either, as it's not designed for side to side loading and don't recommend doing it). Overall this is a well machined heavy vise that should last forever if taken care of. I highly recommend it to a do it yourself person, not sure if it would fit the bill for a professional machinist or not. Rating it I deducted 1 star because of the amount of effort needed to be put into it. Four uploaded photos are attached. Hope this review helps you out.

Qualità - prezzo ottima, buona precisione
Premetto che sono abituato a morse da migliaia di euro, ho voluto comunque rischiare e prendere questa. In genere i prodotti Vevor sono abbastanza buoni, arriva con un foglietto dove all'interno vi è il resoconto del controllo qualità, con le misure effettuate e gli scostamenti. Incuriosito, la appoggio sul tavolo della fresa e iniziò le misurazioni.. gli scostamenti sono minimi, 0.02mm sulla lunghezza, 0.02mm sulla larghezza! Molto buona la perpendicolaritá tra piano e ganascia fissa, fondamentale per squadrare correttamente i pezzi! Ganasce rettificate correttamente... Certo, qualche lasco sulla ganascia mobile c'è, ma considerando il prezzo non si può proprio chiedere di piu! La consiglio? In linea di massima si! Per lavori hobbistici, non di estrema precisione, diciamo per la maggior parte delle lavorazioni che facciamo in casa! Le misure effettive potete vederle in foto. Controllare il piano di appoggio con il banco e verificare che non ci siano ammaccature prima di montarla sul trapano o sulla fresa!!
