Car Cellular Phone Signal Booster & Repeater Antenna 5G, 4G LTE for Verizon At&t Sprint T-Mobile Phones by Cellet

We put them on our deer blind window. Got at least one bar more of signal. One blind had no service and we had enough signal that I could play a movie. I bought two more for our other blinds.

Does nothing, setup is easy, but that tends to be true with snake oil products.

I got this to use in my camper. It actually works... a little. I use it for hotspotting so this might not work you. Put the antenna on a window, couple of inches away from the sides. You want to put the inside part directly over the antenna base. Then, place your phone so that it's touching the phone. I was able to slide a window up to hold it. It is important to have the phone touching the pad. That's it, and from testing signal strength my signal went from -110db up to 105db. Nothing tremendous, but a little gain from having a larger, outside antenna. This may help your signal inside rooms with a window, or in my case inside a camper, but you must leave you phone next to it.

Got this little unit for hunting. Did not have phone service at a few treestands. Wasn't expecting anything but decided to give this unit a try. Have to say I love it when you get somthing to exceeds your expectations. Not saying I can surf the web an all, but I get one bar atleast where I had 0. I can now atleast communicate by text to my hunting party and not have to sit there wondering or them doing same.

No funciona.

Didn't really do or change anything for me at all. There was no change in the signal for me at all, unfortunately.

Picture for reference (and giggles). It’s attached to my pocket via magnets (thanks for the idea, I stole it) ;] Yes, it definitely works. I had to buy one because I’m taking college classes online and the signal in my area at work is sometimes shoddy. Also needed it because certain parts of the property have super weak signal. I sometimes need to use my phone for work. Awkward to send pictures and wait 10mins. Not anymore lol! 5’6ft for reference, no banana for scale. The bars don’t seem to change on your phone but sometimes it boosts up a bar. The real difference you CAN see is how fast it loads. In case you need to know, this is an antenna, NOT a hotspot replacement. Think of it like a fishing pole catching a data fish. Its long body helps pass that signal on. It doesn’t create a fish out of nothing. Great value. Honestly, I bought 1.5 inch sticky magnets, the magnet didn’t stick and ended up peaking off the seal and sticking them to the correct magnets. The sticky part holds so well. No gunk residue.

Doesn't really work. I haven't noticed a difference in signal strength. Easy to set up, but won't buy again.
