These really worked for me.
Wow.. I was in shock when these little stickers worked. I just stuck them, all 3, cuz why not, to the back of my phone. Those areas where I would wait forever for a video to load or a text to go through are not as much of a problem anymore. These are not a miracle device,, don't expect that. They for sure improved my signal though. I mean for a few bucks,, it's worth it. Bought a bunch more,, gonna have friends try them.

Little if any signal boost
Installation on MotoG2024 and Motorola Edge with T-Mobile carrier. I noticed insignificant improvements in signal enhancement on either phone.

Don't waste your money
You get what you pay for! I hate to say it, but these things are worthless. They do absolutely nothing to boost cell reception. Save your money.

As described never know if it actually boost the signal but worth the effort. Used in the past on a older iPhone and it was helpful.

You get what you pay for
Cell service is not any better after putting this in 3 of my phones. To me was worth the try, but you buy cheap you get cheap.
