KKBSTR Cell Phone Signal Booster, Home ATT T-Mobile Verizon Sprint Cellular Repeater Amplifier Kit - Enhance Your 2G 3G 4G Call

We have 2 signal boosters in a remote area, 1 in the house and 1 in the barn. The one in the house was a more expensive well known brand, the one in the barn is this unit. This unit seems to preform better that the more expensive one. The only issue I had was, no instructions that tell you what the readings indicate on the display. What display reading should be achieved for full reception??? It was a guessing game for a couple of days to find what worked best. The indoor antenna is very sensitive and it not only needs to be at the perfect location, it also needs to be pointed in the right direction, Up or Down. Our signal went from "no service" to "4 Bar LTE" after installation.

Got this for my metal garage because phone could not get signal in it. Now have 4 bars all the time.

Very much a plug and play. Plenty of coax to go between the antenna and amplifier and nice exterior antenna with nice mounting hardwares. Tried one of the less expensive amplifier and even following all the quirky antenna placement rules I was never able to get a reliable signal. This one keeps a constant and solid four bar 4g connection. I could do without the fake gain meter gauges but it does look nice in the ads I guess.

UPDATE 08/05/19:Worked great initially, and for about 3 weeks. Then, suddenly, it seemed as though it "wasn't there"... cell phone signal dropped back to what it was before I installed this, and our cellular internet service was completely disrupted. Took a while to figure out that this was causing the disruption. Of course, the 30 day window had passed, but Amazon customer service issued an RMA and I am returning this ASAP. Thankfully, I had used some coax that I owned to do the installation or I would have had to remove that for the return which would have been a major pain. Will probably spend the extra for a Wilson amplifier instead of another cheap Chinese offering. Caveat Emptor.PROS: o Affordable o Definitely increased signal strength and coverage in our houseCONS: o Directional antenna installation was a lot of effort (but would be true for *any* booster)For the price, it's one of the least expensive options out there. Had to do a bunch of research to make sure that I understood which bands our cell phones and wireless Internet modem used to be sure I was buying something that would cover the necessary bands. We live in a very rural area, and before installing this, I could get 2 bars only in a couple of very small areas at the north walls of the 1st floor and 2nd floor and in the bathroom, and 1 bar near the front windows on the west side of the house. Which sometimes it was a stretch to even get 2 bars or 1 bar. After installing this, I get a solid 4 bars in the south end of the house, and only a couple of weak areas between the middle of the house and the north end. So overall, it helped tremendously in the south end of the house and partway past the midpoint of the house. I'm sure this is due in large part to how I installed the directional Yagi antenna relative to the shape of the house, but it is located where I got the best signal indoors... I didn't want to try to install the directional antenna outdoors. Overall, I am very pleased with the results and I would do it again.

Really.....loved it!

Out of the other 4 brands of boosters, this one was the only one that worked with Consumer Cellular. I like also the display showing the different bands, insuring this way that I am tuning the right band.Price and quality, excellent!Alberto Munoz

Very easy to set up. However best to use a cell tower/signal meter to aim antenna.This way as you point antenna you and watch the signal strength. I used network cell info lite (free app)The bars on your phone are not really a good indicator.Improved my signal from 111 db to -87 the lower the number the better.Indoor antenna could be a higher gain. Maybe a 12 DB gain flat panel antenna instead. You do need to be close to the indoor antenna.For the cost I gave it 3 stars if the indoor antenna was better I would have rated higher.

As advertised, this brought my phone signal from nill to 5 or 6 bars and good reception. A better product then the first brand purchased. Covers a large area. Highly recommend this for home or office.
