Customer Ratings & Reviews

Item just arrived today, but quickly installed it with the outdoor antenna sitting in a window, and the results are immediate and significant. We have a metal building for an office, and it sits in a very low lying area. If we want to use a cellphone we must walk out front. Placed the antenna in the front window and set the indoor amplified antenna just 20' away and we have boosted signal by 3-4 bars for everyone's cell phones. AT&T, VZ and Sprint users alike.

the signal booster does exactly what it said it would do. i love it, my signal went from just barely one bar to five. easy to install too i highly recommend.

We have 1 or less bars of signal in our house without this booster. With it, we can not only do texts, but actual talking and sending pictures. I am happy I took the chance.

Where I had no bars at all, now I have four. Thank you for a good product.

Cell signal isn't the greatest here (1 bar mostly/ 2 bars if we're outside), so we started looking at options. Purchased this ZBoost booster hoping it would help. Put it up this weekend. It took a little while. We weren't aware that the exterior antennae had to be 15 feet vertical from the interior antennae so it took a little work to get everything right. Signal strength went up to 2 bars in most areas of our house; some places 3 bars. Some places still only a bar. But we are able to make and take calls in nearly every area of our house, which we were not able to do before. So while the signal strength doesn't seem to have been increased much, our ability to make and take calls is a lot better! As far as I'm concerned, it works!

Works great - can now use phone in the house instead of having to go outside each time.

I live in a 2800 square foot metal house with a metal roof on 10 acres in the country. My AT&T phone had very poor reception in my home. Since I installed the ZBOOST Trio SOHO it makes no difference where I am in my house I have a signal. Great buy.

New office located in a renovated urban warehouse had terrible cell reception. Mounted the external antenna along the side of the building about 20’ high and cell signal went from a weak single bar to 3. No more dropped calls.

I live in area in which I have only been able to use one cell service unit I purchased this booster. This booster improved my signal from one bar to five bars and now I will be able to switch to any cell service of my choosing. This booster is a bit pricing but in the long run I will be able to save money because I will be able to select a cheaper cell company. Thanks BestBuy for offering this booster....

I installed this in my metal shop and now I get better reception inside the shop than I do outside.

Gave us more bars of service in a rather isolated, tree lined area.

We live in a rural area and the closest cell tower is 10 miles away as the crow flies. We live in a metal building with a metal roof. Had zero bars inside until we installed the zboost. Now we have 3-4 bars and we are back in business. Thought I might need a multi-directional antenna but the basic antennae works just fine.

Our home has metal siding with a metal roof. Several dead areas. Now we have lte in all areas of our home! Easy to install too!

zBoost was installed where old analog antenna used to be. 15 foot height differential was met easily. Provide 4 bars near the unit and 3 everywhere else in the house when placed at a central location. Great product.

We had a ZBOOST YX545 and we were lucky if we could get 1 bar on our cell phones in one room with the trio soho we get 3 bars all over the house and out side 20 feat away from the house

works really good, now we can use our phones in the house. We have ATT for our carrier, we now get three and four bars. Before we got this we had to be by a window to use them, now we use them any place.

We have lived in our home 25+ years. We've never had good service inside our house. There was 1 place in the kitchen you could stand to make a voice call. We installed this yesterday. We have 2-3 bars through most of our house now!!!!!

I have only had time to set it up in a temporary place ( propped up in a window sill) and it has already boosted my phone by 2 extra bars where i had no signal at all since the install of a metal roof on my house.

We had a low signal & I couldn't even make a phone call. Bought this & now I have 3-4 bars depending on where I am standing. I can also get on the internet.

Didn't have any bars in my house. Placed the antenna on top of roof and now have 2 bars. Easy to set up
