Works great for 700mhz band on T-Mobile!

Seemed to improve the signal significantly for us to use air cards in our new warehouse while we wait for our network to be installed.

Works as advertised. Where we were getting 1x service we now get 3 & 4 bars LTE.

not the best for commercial buildings. The range advertised is definitely for open spaces and not buildings with walls. The signal drops off fast beyond 75 feet and they seem very directional in that the faces of the units need to be pointed at each other. We are seeing a small improvement but not as good as I had hoped.

This product does what we needed it for. To boost cellphones in our office which
did not have very good reception.
Thanks for your feedback! It looks like you might have selected 1 star when you meant to select 5, since everything is working out well :) But let us know if there's anything we can help you with!

I've used several competitors solutions That was not by choice unfortunately. I started with the zBoost which was a disaster trying to prevent oscillation (to close / to far) and never produced any real tangible results after a TON of effort. I then moved to the weBoost which was marketed under another name when I bought it from Wilson but the hardware is identical. It was a definite step forward but where I live with 1 bar starting out it really didn't get me where I needed to be and again I'm running co-ax cable all over the place. Just bought the Cel-fi Duo+ for Verizon 2 weeks ago and it is the first signal boosting product to genuinely meet my expectations. I went from 1 bar to a solid 3 bars now on the phone, data speeds jumped to between 6-10mbps both down and uploading from 3down/0.3up before the booster and calls no longer breakup. I've noticed calls sound different sometimes now too and I believe that Verizon's Voice over LTE now works because I have enough signal to do it. Also of note, this boosts 100dB whereas I think the others are 50dB and 60dB.
So yeah, the results were good. The real kicker is the install was great. There basically is no install compared to the work needed for the other boosting options. You plug the antenna box into a power outlet where the signal is strongest (I have mine sitting on the window sill). Then you go towards the other end of the structure and plug in the amplifier box. No co-ax from an outside antenna. No co-ax between the 2 units. Just 2 boxes that plug in. There's an easy to read LCD that tells you closer or farther and a signal number that goes up or down to help with placement. Soooo much easier. Getting ready to buy another one of these for my office. Coverage area is great, definitely no issues anywhere in my 2400sq ft home.

Cel Fi performs exactly as advertised.
I have customers who have been waiting for this solution for a while. The area I support from a technical perspective is Health Care. Hospitals have always been notorious for poor in building coverage. DAS is very expensive and network extenders require a GPS fix and back haul.
The Cell fi performed as good and better than I had anticipated. First test out of the box was at home and in my basement where there was no 4G coverage ever, within 5 minutes of unpacking the 2 boxes and plugging them in I had over 8 Mbps down and 1.7 Mbps up. Next day, I visited a customer (hospital) with a common issue. We were unable to get a GPS fix as the location was too far from a window or GPS signal to get the network extender to activate. Again, in record time (this is simple to set up and takes literally minutes to work) the room was filled with notification sounds of text messages coming in to Mobile phones for the very first time. They were ecstatic. The network security resource reported that no rogue devises popped up on his diagnostic tool and he cleared the device for purchase.
My final check for the week was at an airport for Emergency Services Flight for Life where signal issues persisted, again, a significant improvement in speed test results and coverage. The only issue was the inability to pass signal through a Physical Firewall separating the Hanger from the dispatch offices where cinder block and whatever else was used in the building construction. It was not a deal breaker, just needed 2 sets of boxes for each area on either side of the brick fire wall.
Affordable, childs play to install, and it works great. I enthusiastically endorse and recommend giving this a try where not having coverage. Is not an option. Thanks to my friends and solid resources at 3G store for Cell Fi and all they do every day.
