The actuator itself is very strong, however the brackets it comes with for mounting are crap. Depending on what you are going to use it for you will want to get thicker brackets. I used this actuator to modify a atv dump trailer to make it electric dump. Its a 1200lb capacity trailer and the actuator is rated for 1300lbs. IT WILL lift every bit of it too, but dumping 300lbs sheared the brackets it came with, I fabricated thicker ones and have continuously dumped 1000+lb loads of dirt all around my property. Its a little on the slow side, takes 30-45sec to fully extend. Its a really good value for the money though, but if you are going to use it in a heavy duty manor, upgrade your mounting hardware.
