ATNJ KS-C1 3G 4G CDMA 850 Cellular Cellphone Signal Booster Antennas Kit for Small Room Cover 1200 Square Feet Work for Verizon AT&T

The device was easy to install and to setup. It was mostly plug and play, it does not take a professional to do it. I would suggest having the external antenna in a place with great signal. Overall it performs what I need it to do and is great for small rooms.

Easy to set up. My phone shows I have signal but I am still having trouble connecting. I think I need a more powerful booster. This booster would probably work well for someone closer to town.

This thing literally does nothing to extend anything at all. I used a cellular network measuring device to see before and after values and it does not increase cellular network. All this device provides is a red LED light providing some night light. Being a night light it's way too expensive for that feature alone.

Does not appear to do anything for lte.Speed test on 3G is doubled,But in low reception areas it’s lower then lte anyway so for my use case it’s a waste.
