Here’s Why Customers Love Hiboost
Great Product
It was pretty easy to install. It’s boosted our signal all through the house. We live in a rural area where service is something you have to search for about 80% of the time. With this booster, I can have a phone conversation without having to worry about switching hands, walking into the other room, or not having my pinky toe held in the right position(ha ha). Works well for AT&T and Verizon cell phone service, but haven’t had a chance to test any other carriers.
Get more bars!!!
The system took me about 5 minutes to connect to the antenna pole, two minutes to align, and another 5 to cable and start using. Could not have been easier to install. Making the cable routing “pretty” will be the most difficult part. I set one hot spot and two cell phones on my table at my cabin. Both phones had one bar and hot spot was flashing orange, Within two minutes of applying power to the amplifier the phones both had three bars and the hot spot went green. I am about 4 miles from my cell tower but have internet now using a simple hot spot. More than worth it.
Fantastic! It DOES boost your phone signal.
I haven’t got this permanently run yet but I’ve been trying out different configurations. I was Leary at first whether it was going to work because the best I could get was -15 dbm and it said I need to be under -12 dbm. Surprisingly the next Monday customer support called me out of the blue and asked me how I liked the product. I told her my situation and she give me several different options to try. After messing with it for about 30 minutes I was down to -2 dBm. I still have some more playing around with it to do before I permanently install it, but A+ to Hi Boost on customer support.

What's the difference between the 4K Plus and 4K Smart Link?
In addition to different amplification, appearances, and prices, the indoor antenna of the Plus is built in the amplifier. You do not need to run extra indoor cable for the indoor antenna like a Smart Link booster with a panel indoor antenna. Besides the Smart Link is featured with a metal case while 4K Plus comes with an ABS case.
