Cell Phone Signal Booster for All Carriers 3G 4G LTE Car, Truck and RV Use - Multiple Band Cellular Repeater Kit Boost Voice & Data Signal for Verizon AT&T T-Mobile

better than nothing. but not much better. save your money.if you have a semi decent signal it will help clean it up. if you have a poor signal, it makes it worse.have tried mounting several different ways in my Toyota tundra with different distances between antenna and amp, nothing seemed to make a difference. tried it with Verizon, att, sprint, and tmobile. none seemed to be helped in any significant manner. unfortunately, I spent too long testing it to be able to send it back. I wanted to be where the cell signal was actually crap to confirm its abilities . if you buy it, test it quick.

I was skeptical about buying this at first because of the expense. But I do you get phone calls that are clear and Internet everywhere I travel where are used to not get anything.

I'm sitting here in a campground in the Canadian Rockies and I only have 1 bar and I am unable to do all the work I want to do, but with this cell phone signal booster I am immediately boosted to 4 to 5 bars and enjoying hi-speed internet host spotting with my cell phone. Excellent product!!!!

I used it for hotspot and It did not work, connection dropped every 10-15 minutes. It actually works better without this booster. The seller said it needs 2 bars, but why do you need a booster if actually get two bars already?

Did not work for us at all. Guess it was worth a try.

Very unhappy. I mounted on the top of my RV and found no increase in signal strength. I tried in multiple locations. I wish I could return but waited to long.

Seams to work

It works
