System marginal, customer service poor.

My on line chat was terrible. I’m in a very weak signal area, our signal is improved only when we are very close tot inside antenna.

Made the Difference!

I have T-Mobile home internet. This booster has made a big difference for me where I live out in the country. I consistently get 4 bars of service. Installation wasn't too bad and I wish I could have gotten the antenna even higher but that was not possible. Would buy again and would recommend to my friends.

This cell-phone booster is a great way to expand your reach while at home or in the office

For those of us who live in remote areas this is something we can benefit from for sure.I live in the country, and in my area the cell phone service is not the best throughout my home. This booster helps to amplify my signal giving me better reach. The set up can take some time, so follow the instructions.If you install properly and follow the instructions you'll definitely see the results. A great way to make sure you can enjoy calls throughout your home or even in your office if you have similar issues.

I don't have to stand at a window when using my cell phone inside.

Rural installation with signal outside but weak and sometimes no signal inside. Completed the antenna test setup using SignalSupervisor (Android) and was very pleased with inside signal strength. I used to stand at a window or go out on the porch to use my cell phone but I now have the ability to call and use data (with the WiFi Off) everywhere inside (used my phone for a few hours just with the Test Setup).

Great value for the money!

Hiboost was very easy to install. This is a real value for the money spent. We live in the country and it is hard to get good cell service. We can use our cell phones anywhere in the house without dropping a call.
