### ⭐⭐⭐⭐⭐ I’d buy again

### ⭐⭐⭐⭐⭐ Works awesome
*by A***R on August 11, 2025*

Functions as it should for my WeBoost Overlander. It’s affordable enough to replace the cigarette car plug that I am currently using for my toy hauler. Feel solid and well made for the price. Now I can just plug into and outlet to get a better signal from my WeBoost antenna.
