ordered from Revain Prime on Saturday at 14:00. He was at my door at 2pm on Monday. I can only say wow! The product was exactly as advertised and works great.
Pros
Aiming and leveling the horizon can be done with an instinctive movement, and a quick turn of a lever is enough for a firm lock. The rotating ball joint provides 360 degree horizontal rotating fluid movement when the angle is adjusted.
