So first off. If you have a camper topper on your truck or a Jeep or anything in the back of your vehicle this hoist is awesome. I have used this multiple times to remove the top off of my jeep with ease. i thought that was the only thing that I was going to use it for but I was wrong. I have picked up my Quad with this to change the tires and to mount my plow. I have used this to move heavy items around my Garage. Pick something up and backed my trailer under the item and set it down. I love this hoist.I did have a bad experience when I first received my hoist it didnt work. So i got in contact with the company and had a new one at my door in less then 24 hours. The customer service was amazing.Second when I mounted this I used a 2x12 and Lag bolted the unit to the 2x12 and then lag bolted it to my rafters. It holds up so nicely and as I wouldnt try to lift my car with it if you had the right set up and supports i would buy the bigger one and use it that way.Overall I would give this a 10/10 for ease of use ,10/10 for installation, and a 10/10 for overall operation. theres even a dead man switch to stop you from going to high and crushing your own hoist.
