Purchased this product for a theatrical project where I'm using it to drive a scissor lift for a lit sign. So far in my design/construction testing it is working fine. It is a bit noisy and slow (hence just 4 stars) but it was a good bit less expensive than the alternatives I had looked at when seeking an actuator of this size. Not sure how it will hold up since it does have just a 10% duty cycle, but my project does not require much more than that.
