Sanqino Cell Phone Signal Booster for Verizon, AT&T, T-Mobile 2G 3G 4G, U.S.Cellular 2G 4G for Home&Office Dual Band2 Band 5 Mobile Phone Amplifier Kit

THIS is a great product, and actually works. IT WORKS, IT WORKS, IT WORKS. Been using for over a year now without any problems. I do not work for or am I paid for this review in anyway, I'm just analytical by nature and want to share. Here's my story. I live in rural Missouri, closest cell tower is 3-4 miles away. I work from home, in the financial industry, working off secure networks, and w/o this unit I can't function via VPN, or Citrix networks. THIS IS AWESOME. Now for the reasons people have problems and think it doesn't work. Even though this unit is 5000 square feet and I only have 2000 Sqft ranch, my signal is so bad in the first place that I only get 1 room, my office, and about 10 feet further into house that I can really see any amplification of signal. In other words, you can't expect to use for entire house, if you have horrible signal to begin with. So will all depend on signal strength outside that you start with. I might get better around the house if my office was in center of home, but it's on an end. I'm still extremely pleased because I can work now without interruption. You must Test your dbm before and after. Cannot go by signal bars on phone or device, although you will see them increase with use of booster, these are not accurate reading.

Before I bought this product, I was very worried about whether it would be installed or not. After I bought it, I looked at the instructions and it was easy to install. Before I worked on the farm, if I walked too far away from the house, my mobile phone would lose its signal

Installed Sanqino HJ-910 at camp on Toledo Bend, Milam Texas. I had no service using Nexus 6P with an AT&T sim card through Tracfone, my wife was able to text only, with her Verizon iPhone. I located the cell towers in our area, pointed the directional antenna in the direction of the tower and all green lights on the first try, was able to face time with the grand kids after installing. The following weekend was Memorial Holiday weekend, it struggled. I told the wife probably because of us being in a popular vacation place and everyone trying to use cell tower, so I called customer service to verify and they said that was correct what my thinking was, they were very courteous and said if I had any problems in the future to Please call back and they would be more than glad to Help. Since then this product has worked wonderfully except on a busy weekend

Recently moved to a new house and discovered my cell coverage was only one or two bars. Call quality and data speeds were shaky. Thought about switching carriers, but luckily a neighbor recommended using a signal booster and I saved myself a lot of trouble. The Sanqino signal booster got my signal maxed out at 4 bars! Call quality improved and I no longer get dropped calls. Downloads are much smoother and don't stutter like before. What surprised me is that I got this installed in less than an hour after opening the box! Just attach outdoor antenna on roof and point it in correct direction. Hang indoor antenna on a wall inside house, screw in cables and then plug into electrical outlet. That's it! No settings to adjust. Just plug and play. I was also able to get great signal in every room of the house. Definitely a life saver.

We recently moved into a new home in a rural area of the Pacific Northwest, and the only cable Internet is DSL at about 1.5 Mbps, not enough for streaming. Our cell service is with Verizon, and I tried to use my Samsung S7 Edge as a hot spot, which worked ok, but was very expensive. Signal strength showing on the S7 was in the -105 to -100 dB range, pretty average, but we did not have dropped calls and communication was very clear. I also bought a Franklin R910 to try as a hotspot on the Sprint network. It worked ok also, but download and upload speeds on Speakeasy on my computer using the Franklin as a hot spot were in the 3-4 Mbps down, 1-1.5 up, and I wanted to try to improve that. Sometimes I work from home, and needed better, more reliable speeds.We are on the side of a 30-degree slope at about 1,000 feet above sea level, and all the cell towers are west of us with heavy forest and a hill in the way, no doubt contributing to the average coverage. I mounted the outside antenna about twenty feet above ground, fastened to 1 1/4" PVC which is attached to the edge of the roof, and the inside antenna is almost directly below that, so I do not have the recommended twenty five plus feet of separation between antennas. I plan to raise the outside antenna another ten feet or so and will post the results here. Even with that minimal vertical separation (all manufacturers recommend more, or some kind of shielding between antennas) the results were very good. I ran a number of tests, including dB signal strength on the S7 as displayed under settings, about phone, status, and Speakeasy download speed tests on the S7, and on my computer using both the Franklin R910 (Sprint) and the S7 (Verizon) as hot spots.At about fifteen feet from the inside antenna, the S7 showed little gain in signal strength, around 5 dB, but if I moved the phone to within three feet, it showed up to a 25 dB gain, significant, but not very useful if you’re looking for a boost throughout the house. What’s interesting, though, is that the download speeds, tested with the S7, improved dramatically at both fifteen feet and three feet from the inside antenna, almost tripling, 3-3.5 Mbps to 10-11.5 Mbps. These tests were run on Speakeasy using the same server in San Jose, CA. I ran them both in the evening, during peak use, and in the morning with similar positive results. We were not getting dropped calls, so maybe the signal strength shown on the S7 is not as reliable as repeated download speed tests, I don’t know, but obviously I’m pretty happy.I’m an amateur radio operator, and have extensive experience with outside antennas. The Sanqino Home 2G/3G/4G Dual Display Cell Phone Signal Booster is well made, with solid metal construction and coaxial fittings. I would highly recommend trying it if you are having poor cell coverage or want to boost your Internet speeds if using cellular as your access. Be sure to pay attention to the recommended vertical and horizontal separation between the outside and inside antennas. You should also experiment with placement of the inside antenna (mine is in a base cabinet) to see if that improves the strength further away from the inside antenna. I’ve learned over the years that antenna installations require testing and tweaking.
