If you are going to use the top of the line covers (heaviest) this is not for you. After 6 months one of the shocks broke and now after 2 years both arms are broken.

The problem is that the side arms are not long enough to slide into the support bracket for a stable fit. I am going to find a dowel or similar support to slide into the hollow ""pipes"" of the side support arms to make them strong enough to support the cover in the lifted position. The Covermate III I had previously snapped at this point. My cover is one of the larger ones so the absence of sturdy support arms needs to be addressed IMHO. I would only recommend this if the buyer is willing to modify it as mentioned.

Installation was easy and directions were clear

I was looking for a replacement for the lift my hound dog destroyed and this one is a perfect fit, thank you SpaDepot!

It was good for about a year, then piston kept popping off. Eventually the red safety tab gets brittle and breaks. I would've recommend if you have a heavy duty cover.
