## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great!
*by E***Z on January 29, 2025*

The price can be intimidating but know when you need signal it works. I spend a lot of time in the back country hunting and have had pretty good signal. The quality of the unit is great

### ⭐⭐⭐⭐⭐ Good quality
*by C***. on August 25, 2025*

Made just as good as oem

### ⭐⭐⭐⭐⭐ Clearance and clarity
*by A***R on August 11, 2025*

Fast shipping as always. This did the trick no needed a few more inches to clear the top of my toy hauler to get a better signal. Functions as it should! For the money, it’s worth it for better clearance and clarity.
