babi One Step Ovulation (LH) Test Strips, 50-Count

For me, these strips are better than wondfos. First, you don't have to use room temperature urine as you do with wondfo, and second, I believe they are far more sensitive.The first month I used them I was frustrated because I had never used opks and I was testing too early in my cycle and kept getting "almost" positive lines (I recently had an ectopic pregnancy, which changed my cycles so I didn't know when to test as I didn't know when I'd ovulate). At the time I should have been testing, I went out of state and left these behind. Thus, I was the problem, not the tests.For my next cycle, I ordered wondfos and used them alongside these strips. With the babi tests, I almost always get a pretty dark line, but it's nowhere near as dark as the control unless I'm getting close to my surge. I get a less obvious line on the wondfos. The babi strip was the first to detect my surge, and it was an obvious positive. I tested with wondfos with the same urine sample, and they were negative, although just barely negative. Wondfos tested positive with urine collected 4 hours later - babis were positive for this sample as well. Babi was also a clear positive the next day (day 2 of the surge), whereas wondfo was still positive, but harder to read. Wondfos went negative on the night of day 2. Babis didn't go negative until day 3, which indicates that they are more sensitive at detecting lh levels.In short, I highly recommend these strips. They were, for me at least, more sensitive and easier to read than the wondfos. I'd buy a bunch if you've never used them before to get used to the way they read and be sure to test at least twice a day when you're getting close to ovulating. And if you're a POAS addict like me, I'd also buy the wondfos if this is your first cycle testing so you can verify the results of the babis.

Positive feedback:1. It works.2. The price is good, considering how many strips you get (waaay better than what you would pay at a typical grocery store)Negative feedback:1. It was more difficult to use than the typical "sticks" that you pee on. These are strips - not sticks - so you have to pee into a cup and then dip the strip into the pee, which was fine with me when I ordered them. I had never used strips before. The process became complicated when I had to figure out what cup I was going to pee into. (A friend suggested buying disposable paper/plastic cups, but that seemed weird to me, so I used a regular glass cup and simply washed it every day. It wasn't that big of a deal, but wasn't entirely convenient.) The other problem was that I peed on myself a few times until I figured out how to position the cup. But...maybe that's just me. I do tend to be a little uncoordinated.2. The one time my strip showed up positive, it was so difficult to tell whether the line was darker than the other line, I had to go and ask my husband. Maybe it isn't always hard to tell, but it was that time. Every other time I've tested it has been negative.My advice? If you're on a budget and don't mind peeing into a cup, these are great. If you have the money to spend, it might be easier for you to buy the sticks. Also, only buy these if you're okay with trying to decipher lines on a strip. Again, it wasn't the end of the world, and I will continue to use these, but if you struggle with that, these may not be for you.

I can say that these test strips really do work. I have bought the babi brand tests strips from a couple of different sellers here on Amazon, and one thing I am noticing is to pay attention to the dates on the package. Each individual package will have 2 dates on them; one is when the test strip was manufactured, and the other is the expiration date. These test strips are good for about 2/ 1/2 years, however, tests strips with a more recent manufactured date are much more sensitive than ones with older dates.For example, the test strips I bought from this seller (that I am writing this review about) has a manufactured date of January 2015, and they work extremely well and are very sensitive. The other test strips that I bought from another seller here on Amazon have a manufactured date of December 2013. And while these older tests do seem to work once you have an LH surge, they are definitely not as sensitive as the newer ones.Besides paying attention to the dates on the packages, I also recommend paying attention to how diluted your urine is when taking this test. The more diluted your urine is, the less likely these tests strips will work properly; as your urine will be too diluted to detect LH. So I recommend not drinking anything for several hours before testing, or holding your urine in as long as you can. The darker the urine, the better (at least for me anyway).

These test strips are good for the price. I will say however, as a first time user of Ovulation Prediction Kits (or OPKs) I was a little confused about how to read the strips. I prefer the Clear Blue Easy Digital Ovulation Kit. It takes the guess work out of it. I basically bought these so I could test twice a day. I used the Clear Blue ones in the morning, and these Babi ones in the evening. Something I did notice was I got my first positive in the evening using these strips. The Clear Blue test I used that morning still showed a negative. I don't know if that means the Babi brand detected my LH surge sooner than the Clear Blue brand, or if I just got my surge a few hours after I tested with the Clear Blue brand. These did the job at calming my anxiety down over missing my surge by allowing me to test more than once a day. I suggest these if you are a little concerned over missing your surge, or if you just want to have extra as a back up to a higher end brand.

Got these and there are 50 in the package. It came with instructions too. Not sure if they work but we will see once I try them.

I received bad batch. There is a faint line during ovulation. And it takes forever to get a result!
