KKBSTR Cell Phone Signal Booster for AT&T T-Mobile Verizon Sprint - Enhance Your 2G 3G 4G Call

This thing is seriously a life saver. Went from 1 bar 4G LTE to 4-5 inside my house. Install was simple, plug and play. I have terrible satellite internet at my house so using wifi isnt really an option. And now I can actually have phone conversations without them cutting in and out.

I had a metal roof put on my house and the cell signal went away. This product boosted the signal to 4 and 5 bars. Thecompany's rep was great. Answered question the same day. No more dropped calls or dead zones. The house is 2700 SF and it powers the hole house end to end.

I live in a small town with decent signals At&t, Verizon, etc. I am with cricket wireless which is under At&t and the signal in my basement went from a weak 1 or 0 bars to perfect full bars with anything barely working. Voice, data, and text work as they should with this product as if I was outdoors using them normally. Definite recommend. Sadly I cant confirm if it works the same for other networks since I cant test it out, but they should.Also as a bonus, they included a rectangle mousepad with the dimensions of about 7inx10in. Awesome since I have a pc.

We could not get any cell service in our barn. "Husbands Man Cave" I got no problem reaching him now. Works great!! Watch u tube " how to install". easy peasey!!

Moved into a house and it had propanol(metal) roofing!! Before installation of this product I was barley getting on bar of signal, now after installation I have full bars!! This fixed my problem 100 percent. A must buy in my book, super happy

Works great we went from no signal inside our house to having 3 to 4 bars

On the plus side, the cell booster increased the bars on my phone from 1 to 3 so now my phone is useable while I'm in a back room of the house. The tech support was reasonably good with very quick response and the unit itself appears well made. On the negative side the documentation is nearly useless - it doesn't even tell you what gauges on the electronics are measuring. Worst of all the indoor antenna emits very little power and so the signal drops off rapidly. at 5 ft from the antenna I get 5 bars; 15 ft away I get 3. The lesson here: place the indoor antenna in line-of-sight and as close as possible to the location you want to use your phone.

We installed this cell signal booster on our roof. Outside our house we can get 1-2 bars. While the booster did amplify the signal, we have to stand right beside the antennae for it to amplifier from one bar to 3 bars. As soon as we walk away just a few feet, we lose signal. This product didn’t work for us.
