Super easy setup. Works well. It will usually give me one additional bar (dot) on iPhone and sometimes two dots.
I would buy it again.

I tried the unit when I was driving an area that I don't normally have reception in. So I stopped, dropped the phone in the carrier and hooked the pwr and antenna up, went from no bars to 2-3 bars. So I made a call out and was pleasantly surprised. Only thing I don't care for is the way the cradle hooks on to the mount. If you pull the phone in and out of the cradle several times it tends to come off the dash mount easily no matter how hard you push it on. It needs a better secure mount.

If there is a signal this will boost it. My only complaint is how hot the product gets. I'm told by their customer service this is normal and won't hurt the phone but I have had times where my iPhone shows a temperature warning. Just be mindful and cool it down if you are on a long drive.

This the best booster out there. I have tried many different boosters and have traveled to desolate areas and this booster always works. Well worth the money!

This booster is very good, of course you can't expect to get reception everywhere, but I'm a truck driver, in the oilfields of Soth and Central Texas and in areas that I would usually have a dropped call, the signal still breaks up a little, but the call isn't lost so I don't have to call the person back multiple times. For someone like me who is on the road so much and must keep my attention on the road, it is an invaluable tool that is worth the expense. In a day where I would normally have 10 dropped calls, now I might have 2.

This was a helpful signal booster with our family traveling in the mountains. Only drawback is that it gets really hot and makes our phones hit.

I work in southwest Texas, in the middle of only God knows where. Before I bought this I was I would have to drive around town looking for the sweet spot where I could get good signal. I haven't looked back since. This product works. My only drawback, which is purely an environmental issue is my phone overheats when it's hot in my car. When the a/c is on or the outside temp isnt boiling like it usually is in the Texas summer it's all good.

Bought this for use in west Texas where signal is very poor for most carriers. The results were not that great with only 1-2 bars boost in signal on AT&T and about 1 on Verizon. Maybe it is just the location, but not that great of a device. At least it is somewhat affordable compared to other units on the market.
