Good singal booster
I can’t believe this device can make it my phone signal this so strong, before using this device, I was always have problems with phone call quality, now no more this issue, I can clearly hearing with every phone call.

From no reception to streaming Netflix!
I'm a novice when it comes to cell phone technology but I bought an international phone that won't allow me to use wifi calling and our home internet is unrelianle at best. With no signal booster I have to stand in one corner of the house to make a phone call and there is absolutely no internet connection on my phone. Now with this signal booster I have full bars and I'm able to watch Netflix on the stadard def with my phone.I'm on at&t gsm network so I can't speak for other carriers technology but this works great if you have at&t or similar providers.

You need this when you live far away from city
Lived in the rural area can be a pain for non-Verizon user, I am not going to pay 60 per month.I had been using Tmobile for years and usually get a bad signal when I get home.Requested a signal booster from Tmobile is a joke, the booster really does nothing to help.Although it was not a fun job to set this unit up, approx. 2 hours just to get it to install correctly, but it does increase my signal by a bar.

Not too sure how I feel about this yet.
This product works if it’s a sunny day with no clouds in the sky. I went from have 0 bars to at least have extended and even 3G sometimes. Still can’t make or take any phone calls though. This also wasn’t very helpful since I live in an apartment complex and I couldn’t actually mount the atena to the roof (I used a tree). This product also didn’t come with an instruction manual so I had to do some research online.
