Stroke 10mm 20N 0.4 Inch Mini Linear Actuator 12V Force 4.5lbs Electric Linear Motion Actuators High Speed 1.2"/sec for Robotics,Home Automation with Mounting Brackets

Great

These work great. I used these as part of a dust collection system, to open/close blast gates. Worked great

Mostly work as their supposed to but very slow. I got the 1 inch version and it takes 10 seconds to open. Had to time it to program a puzzle box. Way slower then i thought it would be. But works fine for what it does

Works as advertised

Functioned perfectly for my custom designed Bambu Lab X1C remote controlled vent system. Yes it was a crazy idea but got stuck in my head and I worked on it until I made it a reality! PLUS it was a fun and challenging project!

It literally fell apart in under 24 hours with possibly two cycles opening a door with no load. The old actuator on my chicken door finally died so I got this one because I don't need a 200 lb actuator to swing open a door on hinges. Well it literally fell apart the next day when I went out to check my coop after finally welding all new brackets and setting it up. It literally pulled itself apart which I don't understand how because there is very little load pulling the door open and once the door is open there's no load on at all. Maybe I got a bad one, maybe it's just junk, either way keep that in mind

Ok

The 2” linear actuator functioned once and then quit working
