Excellent product.  Mine came with batteries, so no cost to get them running.  Would gladly buy again.

As sion as I receuved it I installed one on the back of my cell phone. That is what I misplace most often. It is thin so it sticks well on the back of my cell. I replaced the 2 sided sticky pads with thin 2 suded tape as the sticky oads that came with it were to thick to use. I gave it 4 stars instead of 5, because the opener to the battery compartment was missing. Too bad because otherwise I really like it. After I bought it I found they came out with a rechargeable version, which I would have liked better.

I love it it deep save us from a lot of activation

I like the fact that there are six tabs.  Unfortunately, my brother’s remote works for my keys also.  I guess it’s good we don’t live in the same household!  Overall, I like it.

Perfect

We love this thing! Very handy and loud!

Our daughter & son in law sometimes can’t find their keys in their hectic lives. This was the perfect answer!

Reliable, Very Loud, Easy to Assemble.
As for ESKY product support services, excellent. I asked about purchasing extra remotes, just in case I lose the remote, and the vendor communicated in an amiable way and offered suggestions;  I call that professional and excellent after sales - goes a long way. I am now going to purchase extra sets for my sons and sister.

Arrived quickly. I purchased 3sets as gifts, and they were a big hit !

This was easy to set up and works as well as I could test it for now I'm in a walking boot from an injury. I will add more in the future. It will be attached to my drone.
