I bought this item to increase my cellphone signal in the granite, tomb-like building where I work. The good news is that the item works as advertised. It substantially boosted the 4G signal inside my workplace. The bad news is that it ONLY boosts 4G, which means that if your cellphone doesn't support VoLTE (which means "Voice Over LTE") -- and mine didn't -- then it's not going to improve your call coverage (although it likely will improve your data coverage). So, if you are looking for better cellphone reception and coverage, I suggest that you check to make sure that your phone supports VoLTE before you buy this item.

Signal was great, easy to setup. only downside was window unit broke after 2 weeks of use. started making a clicking sound and wouldnt power on at all. had to order another one. Edit: These have to be sold as a set with matching serial numbers. the items will not work or pair unless they are matching. be wary of buying any singular unit as it will not work for you.

I hate the fact that I had to buy a signal booster to get cell service in my home, thus subsidizing T-Mobile's poor coverage and failure to build new cell towers. That being said, this signal booster does a great job of pulling in very weak signals. My phone went from 0 or 1 bar intermittently to a consistent 5 bars. However, I also want to say that this is my second signal booster. My first one was a used one that I bought on eBay. I don't know how old it was, but it died after only using it for 6 months. I don't know how long this equipment will last. Fortunately I got the one I have now for a really good price.

The advertised range is exaggerated. The trick on a big house is getting the base unit in a central spot that also has a good power level. Without getting into too much detail, basically you get a higher power level the further you are from the window unit. But if the window unit is at one end of a big house and the base is at the other - sure, the base will put out a good strong signal but it's not necessarily going to cover the whole house. This makes sense for those who have the unit. Suffice to say it works but don't expect miracle coverage. For that you may need more units.

Where I live is like a Bermuda triangle of cell signal. I was with Verizon(supposedly the best coverage network) for more than 10 years.. Never had a signal.. doesn't matter 3G, 4G... I was had it with them and move on to T-mobile which has marginally better signal showing than Verizon, anyways, The signal was there but, never stable... so I was looking into products that can boost signal, many of them looked promising, but expensive. But, this product is actually the one that I can afford and has further the coverage area in my house.. Not perfect but It definitely improved my poor signal problem.
