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.
