This hydraulic lift is fantastic. I bought it to rack and unrack servers and UPS battery backups. I lifts 150lbs easily and I could precisely position the equipment and slide it into the rails without an issue. It comes with a textured mat but it isn't glued and can be easily removed so whatever you're lifting can easily be slid on and off.
The only downside I have found is that it takes a lot of pumps to reach it's full 50" height. Also, if the cart is empty, it takes a little while to lower. If there is a load on it, it lowers much quicker. It's apparently adjustable but I didn't mess with that.
