Before getting the zBoost, the very best signal I could get in the house was 2 bars - and that was remaining motionless in a certain spot, if I moved the call would drop. Once I installed the zBoost I have gotten up to 4 bars in the house, and can even make calls from the kitchen, where I could never get a signal at all before. The reason for the 4 stars instead of 5 is that every so often the green light (indicating a good signal) will turn to a flashing red. When this happens I must unplug it from the wall and plug it back in, and in seconds it's back to a solid green signal.

I tried the system out for two weeks and thought I had a winner, until I really tried to use it fully. I got twice the bars on my phone, BUT it didn't change being able to get text messages through either direction. No Network available is what I got messaged even with 3-4 bars! So I returned it................

This was a difficult product to install, requiring drilling through the roof, running cords through walls. it didn't work at first till we ran more cable to get 15' vertical drop, but now it hangs down and has cords running across floors. Cell service seems to be better, but still not great. Also, had to get 2 people to install (who wants to be on a big ladder with no one around) and that was expensive as well.

I have owned one for some time and have bought two more for family members.

For anyone who lives in a rural area this is the product for you! I went from no service inside my house to 4 full bars!

So glad I purchased, it has increased signal and wifi. Would recommend to friends and family.

Had little cell coverage inside my house. After installing the device we had better clearity on calls and fewer dropped calls.

Easy to set up. Took maybe 10 minutes at the most. Getting a signal at my hunting camp where we had no signal before. Would recommend a larger external antena to keep signal from fading sometimes. Great product.

This works very good for the house. Easy to intstall l and get it up and runnning.

I returned this item as I could not install it in my apartment don't know if it was good or bad

I have little to no cell service at my house but now I get 3 bars. It works great, is very fast, and installed in 15 minutes. Great product

My home doesntshow any network.. this really helped me boost the network... Thank god... !!

Nice box. The equipment was easy to install. The signal never got better.

I was excited to receive this item and it was a breeze to set up however it didn't work in my home. I have one to two bars of service but my calls often drop. I thought this would be a solution but it wasn't... It didn't help at all. An outdoor antenna was necessary.

I bought this item thinking it would be easy to set up. The antenna has to be mounted 3 feet above any metal and at least 15 feet above the base unit. I didn't know an antenna was included or needed. I had to borrow a 40 foot ladder to get up above the 2nd story and that required lifting I was not ready to do. And after all that My phone signal is still not as good as when I'm out and about.

From no service to full bars! It really does its job!

It does a very good job it went from 0 to 1 bars to3 to 4 bars works great

Experienced no improvement in my cell phone signal

I could not get cell reception in my mobile home due to faraday blockage. bought this repeater, now I can talk without going outside!

The thing worked for 2 days. Then quit working. I called the company. They said they would send my a return label via email. I has been over a week no label. No cell service at my house. I drove 4 hours from where I live to pick this up because my boss was on vacation and I need to take the office phone calls in the evenings. I have had contact with 3 "managers" still no resolve! Don't waste your money!
