I must admit I had my doubts with this product. I never really thought it would work and when I finally got my hands on it and set it up, I was shocked to see strong 5 bars of service on my phone. I have to say I'm beyond pleased with this one.

    My house is surrounded by dense vegetation. After installing the kit myself, my mobile phone signal went from weak to a steady 3 or 4 bars of 4G. No more delayed messages or dropped calls. Internet connectivity is now fast and reliable. —it's affordable, and the performance surpasses satellite Internet. Many thanks!

      My husband suggested we relocate and not long ago we relocated from town to a rural area. We have our own house now, but cell coverage here is terrible. We bought this booster and crossed our fingers that it would work. Luckily for us, it did, and we get a strong 4G network in every room in the house. Sometimes I forget we don't live in the city anymore.

        Purchasing this unit for our office has proven to be a wise decision. It seamlessly caters to the needs of all three of us, delivering exceptional speed across the board—calls, download speeds, and streaming. I can efficiently handle my emails, and the remarkable clarity of voice calls continues to impress me. I recommend it to anyone seeking relief from the frustration of dropped calls and sluggish internet.

          In general, this device does fulfill its intended purpose. I've witnessed a significant improvement in my signal strength, going from a mere one bar to a solid four bars indoors, which is certainly commendable. However, there are a couple of aspects that could be significantly improved: The use of N connectors presents a notable inconvenience. When you need to drill a hole in your house's exterior to accommodate the cable for the outdoor antenna, the sheer size of these N connectors becomes a challenge. This results in having to create a substantial 1-inch hole for a cable that's only about 1/4-inch thick. This not only seems excessive but also complicates tasks like routing cables through walls. Switching to SMA connectors on the amplifier end could have resolved this issue neatly. Unfortunately, the user manual falls short in terms of clarity and utility. It lacks guidance on how to optimize the unit's performance and fails to provide valuable information on various aspects. Consequently, users are left hoping that the device will function optimally upon installation without the need for any adjustments. Overall, the unit does deliver on its promise of improving signal strength. However, there is room for improvement in terms of execution, particularly regarding connector design and the comprehensiveness of the user manual.
