I park at Pier 32 parallel against a fence and between two other boats, so even though I'm pretty good at it it's still a bit of a PIA to get the boat in and out. And those times when I park in my driveway it's very difficult because I have to go parallel to my house.
It took about 15 minutes to install. The unit is entirely powder coated and everything appears to be very high quality and solid. While I was putting it on another guy at the ramp ran over to have a look. I took a video of him moving it around. He was very impressed by it as well.

It's extremely easy to use: Pull the steering handle up (which unlocks the brake), rotate it the direction you want, and crank to move the boat. It's got two gears, a very easy low, and a bit harder but faster high gear. It easily moves the boat in any direction in just a few seconds and makes lining up on your ball a piece of cake.
One thing I really like about it is the entire mechanism comes entirely off the mount plate by pulling a hitch pin out, which means that I can put it in the back of the truck when the trailer is on rather than dipping it in the salt. That should make it much longer lived than my other trailer jacks. You can also carry it on the mount plate if you want.
Bottom line: Works as advertised. Quite pleased with it.
