Does the task as claimed.
It’s a good security alarm. Compact in size and very easy to install. You just need to remove the adhesive cover tap and just fix it. Keep in mind to put both the items closely otherwise it will not work. So overall a good alarm set to purchase.

1 piece disfunction
i have fixed the alarms on our 3 main doirs that opens towards main road, before fixing i tested on spot about the alarm function all 3 were working good with loud sound, but the 4th one is faulty and disfunctioning the alarm is ringing even when the 2 pieces of system are closely held i dont know what to do with this faulty piece, i would be thankful to amazon if they help me getting a replacement for faulty alarm piece iam ready to return the faulty alarm piece to manufacturer to check fault i bought after seeing good quality reviews by many buyer, but i found that the navkar systems management is not checking the alarms before dispatch

Not worth at this price
The product looks over priced as the quality is very cheap. Looks like a toy. Adhesive area is very weak. Just after installing, it fell off from door. My suggestion- 1. Do not expect much from this product. This is just a temporary solution for your need. 2. Over priced at this price. 3. If you are seriously looking out for security alarm system, then look for something else.
