The product works well. Signal strenght is better than before even more now (january) because there are no leaves in the tress around my house. During the summer, the signal was a bit weaker BUT still better than with no booster.

Delivered on time. Will edit later with details on effectiveness of the booster.Update:Pros: Inexpensive booster, it improved call quality, and it was easy to set up.Cons: Range on the inside receiver is very short (under 10 feet) and the instructions could be better.We installed this booster to improve cell phone call and data quality at our cabin in eastern Prince Edward Island (PEI), Canada. The nearest cell towers are 15-20km away and signal strength usually sits at 1 bar with poor audio quality and frequent call drops. Under the right conditions, the booster was able to improve signal strength by +25dB and get up to 4 bars, greatly improving voice call quality.Before purchasing this booster, confirm which cell phone bands you're receiving in your area and buy a booster that suits those. There are instructions online, in this product ad description, or I'd recommend the Android app "Network Cell Info lite" (free) to confirm the band and signal strength. The bands we received in PEI fluctuated between 4, 12, and 13.The package included everything in the description and there was enough cables to use in our small cabin. The outside antenna is light and looks tough enough to handle east coast weather. A longer mini-coax cable could be needed for a larger home or taller antenna mast. The instructions included were decent but were missing some items, such as weather-proofing the cable junctions with the included rubber tape. Watch the video in the ad description to see how to apply it. Hooking up the cables and hanging the inside antenna was easy. Installing an exterior antenna mast (not included) would be more involved.We didn't end up installing the outside antenna on the cabin exterior and just attached it to a wooden stand on the second floor and pointed it out a window at the nearest cell tower. It took a few tries to orient the antenna to get the maximum signal improvement. Look up where the cell towers are in your area and point the antenna as best you can.I was disappointed in the range of the inside receiver, where you need to stand within about 6 feet of it to get a noticeable improvement in signal strength. I had hoped that placing it centrally in the cabin would cover the entire building, but it did not. We moved the receiver adjacent to the kitchen table and had people sit next to it when making calls to make sure they got some signal boost.Overall I am happy with the performance of the booster, though I wish the inside range was a little longer.

Update: the booster no longer transmits after 5 months of use. The LTE and CELL lights are a solid yellow. Will update after speaking with customer support but so far Im not impressed.Original review: I like that the booster covers a wide range of channels. Installation was simple enough and the kit came with everything needed. The booster was successful in taking the good outdoor signal and bringing it into the basement. However, the range/transmission db on the directional indoor antenna is quite poor and certainly no where near what's been advertised. Our basement is unfinished and the signal strength starts to drop noticeably for every 10 feet away you are from the antenna. I do not believe this to be a problem with the antenna, rather the transmitting power of the unit is likely much lower than it should be to reach the claimed distance. Overall, it's an OK transmitter that covers multiple bands - but lacks in the transmission strength.

Very happy with my purchase, I live in the country with poor cell phone service, this booster worked for me. Easy to install and increased my signal from 2 bars up to 5 bars no more dropped calls . Installed the booster in my basement ,outdoor antenna on the peak of the roof and indoor antenna in the first-floor hallway Good product for the money.

Purchased this signal booster to improve cell service in our steel-clad shop. It was easy to install and took less than 30 minutes. My 13 year old son did the climbing for me and mounted the antenna to the edge of the roof (we didn't need the antenna mounting pole that is sold separately as the antenna has an adequate mounting bracket attached to fasten right to the fascia).Hook up was straightforward and the increase in signal strength is amazing! Used to get zero service in the shop, now we get 4 bars and calls are not dropped. Well worth the investment. Plan on purchasing a second booster for our home to increase reliability there too as we live in an area with spotty service. Seller was great and sent follow up to see if everything was OK (I returned the antenna mounting bracket since we didn't require it). Highly recommended.
