  • This thing works! Don't waste your money on cheaper solutions, or more expensive ones.
Color: 10k Pro
I bought this as hurricane prep, because the last major hurricane we had roll through southwest Florida took out our cable internet for 4 months. Well Ian just rolled through, and here we go again! Rural living and there is barely cell service outside (like you need to go up on the roof and hold the phone above your head with your fingertips to send a text message). Normally we have gigabit cable and use WiFi calling and all is good. But when the cable goes down, especially for 4 months, it's carrier pigeons and smoke signals. I've purchased other boosters for half the cost of this one in the past, and ended up returning all. Often they only support one or two frequencies only, inside range is restricted to right next to the indoor antenna or the same room, and outdoor antenna aiming is a guessing game requiring a compass, Cellmapper app, and a steady hand. This device solves all those issues and I wish I had bought it earlier. The free app allows you to easily adjust the antenna and see the results in real time, even when up on a ladder away from the indoor unit, so there's no guessing. Perfect alignment in minutes. As you can see, my signal levels are barely in the acceptable minimum threshold for this unit to work, yet work it does, and very consistently and reliably. And compared to more expensive units, it automatically amplifies all the carriers simultaneously, instead of locking to a single one. And one of the biggest issues with repeater units like this, signal loopback, is essentially a non issue with this unit. It gives you a clear indicator light to warn of loopback until you get the placement right, and even indicates various degrees. It's the only unit I've found that will allow the average non-pro installer to get the most out of it and tune everything perfectly, and do so in minutes. Installation was an absolute breeze and all hardware and cables needed were in the box. Customer service is excellent, with instant answers from a live rep (even followup phone calls and a direct contact number, no automated prompts). You won't need it because it's so easy, but if you do, they are there and they'll contact you to make sure everything is good before you get a chance to contact them. For now I just threw this thing together after the hurricane, but I will be doing a proper permanent install soon. But ultimately, it's performance that matters. I went from no data (calls only) on Verizon to consistently over 50mbps 5G on barely any signal outside, and that's INSIDE my 2700 Sq ft home without even the secondary indoor antenna hooked up (just the main unit). And I went from sometimes (when I stand near a window) 1mbps T-Mobile 4g in the house to 15+ mbps 5G consistently. Both connections are now strong enough to make and hold a phone call from anywhere in the house, and can be used for data and hotspot in case of cable outage. And it improves the battery life on all my phones while they are home, since they don't have to work as hard to constantly hunt for a signal. And best of all, unlike WiFi calling or those cellspots that the carriers send you, it doesn't depend on home broadband to work, and it transitions active phone calls from tower to repeater and vice versa flawlessly and seamlessly without dropping the call, which is important if you live in an area where you have cell signal outside but not in and don't want to lose an active call every time you step into the house. If you live in the middle of nowhere, your city friends will be impressed that you have flawless 5G coverage inside your house and wonder how it's possible. Now keep in mind, you do have to have some sort of coverage outside for this thing to work. But at least in my case, I was able to mitigate that with altitude and essentially a clear line of site to the closest cell tower, even if it is out of range when at ground level. Only complaint I'd have is lack of band 71 600mhz. It seems no repeaters on the market support this. If it did, I could probably get away with T Mobile home internet as my primary and save a whole bunch of money while still enjoying blazing fast speeds. Get a good solid pole to mount it on (pole mount for outdoor antenna included), walk around with the outdoor antenna on the cable first while watching the app, and find that ideal spot. Mount it, and forget about it. It just works. ... show more

  • Excellent Signal Booster with Easy Setup and Stellar Support!
Color: 10K SL
I purchased the HiBoost 10K Smart Link to improve our spotty AT&T signal at home, and it has exceeded my expectations in every way. From the moment I opened the box, the installation process was smooth and straightforward. The kit came with very detailed instructions, which made it simple even for someone like me who isn’t especially tech-savvy. One of the standout aspects of my experience was the personalized support from Noah at HiBoost. He walked me through a couple of questions I had about the best placement for the outside antenna, and his advice made a noticeable difference in performance. It’s rare to get that kind of responsive and knowledgeable customer service these days! Once installed, the results were immediate. I saw a major improvement in both download and upload speeds using AT&T Wireless—our download speeds more than doubled, and upload speeds, which used to be practically unusable, are now fast and stable. This booster turned our frustrating signal dead zone into a reliable coverage area. The HiBoost Signal Supervisor mobile app is another highlight. It’s clean, easy to use, and made fine-tuning the signal strength a breeze. I loved being able to monitor performance in real-time and make adjustments as needed without climbing back into the attic or checking bars manually. All in all, I’m extremely satisfied with this purchase. If you’re struggling with weak signal and want a solution that’s easy to install, well-supported, and highly effective, the HiBoost 10K SL is worth every penny. ... show more

  • HiBoost works and it is bundled with great service.
Color: 10K SL
Living in what used to be a wooded rural area. There are probably several factors over time that have impacted the quality of the signal in my situation. More housing going up saturated network, and many more. Both Verizon and AT&T have a large presence in the area. In my case 4500 sq feet 3 floors we were losing calls more frequently. Unless one puts up an 80’ plus antenna there is no line of site to a tower, too many trees in the way. Looking at the options, the reviews and need opted for the Hi Boost, booster that covers 6K square feet. Two pictures of the antenna and signal at the antenna site. The last picture is the signal strength in the house two rooms away from the indoor antenna. Installation went well, read the instructions then followed the directions. Due to placement, I ended up using a 50’ antenna to booster cable. Eliminated the window pass through option so reduced my cable connections and loss there, I didn’t do all the math for the loss/gain but 50’ is working well. Planning to put a lightening arrester in line now that I see how the connections are mated. Once the booster was on and registered via the Signal Supervisor app the support team kicked in and offered assistance, with plenty of follow up. There was a bit of challenge syncing my app/phone and booster, had to have all the information for registration ready or stuff started timing out. The result was to plug in the booster near the antenna, sync and register with the app. The support team followed up with the installation progress and offing to lend a hand. I didn’t need any extra assistance but the follow up was appreciated. Once fully installed support confirmed via pictures of Network Cell Info lite version and pictures of the front of the booster that all looked good for the installation. The only down side I have is regardless of Hi Boost, a booster that covers what is needed. With 3 floors, plenty of walls and other obstacles, the 6K sq foot coverage leaves a lot to be desired. I struggled selecting the correct booster for the application. With Hi Boost I was on the fence between the 6K and 15K (two antennas). The booster is working great and I would recommend it to others. Support is excellent, can’t go wrong there. Overall, the booster works well I don’t lose calls. If and when the time comes for switching to a 5g internet service provider, I have great signal strength in several rooms of the home so that should not be a challenge either. Again, I recommend the Hi Boost cell phone booster. ... show more
