Review on Self-Locking Reversed Rotating BRINGSMART 20Kg Cm by Mike Snedeker

Purchased BringSmart 12V 16rpm worm gear motor and Greartisan 12V 25rpm motor. I wanted to photograph them side by side so you understand what you are paying for. The small one was about $15 and the large one was about $30. This is April 2021. I am planning to build a 12ft motorized outdoor projection screen. I believe Bringsmart will have enough torque for the project. I feel like it's worth the $15 more. It's twice the size and has cable ports and mounting holes on the front and back. However, if you're doing something smaller, you might like the space Greartisan saves. The small one is about 3 inches and the larger one is about 4 and 1/2 inches long. Haven't used it yet but feel compelled to give a review. So I'll give it five stars and come back and adjust it if I have any issues.
