Review on Harken - Overhead Garage Storage Hoist for Cargo Box, Self-Leveling & Safe Anti-Drop System, Simple One-Person Operation, Smart Organization for Garage by Mike Davan

It's great. I was able to place the kayaks over the garage door to maximize space in the small garage. You'll need a bit of fiddling to get the knots in the right place and adjust the straps properly. The only complaint is that the silly metal buckle on the strap is entirely unnecessary and can scratch the boat; I wrapped them in white tape. I pull the boot through the straps without using a buckle. I would have preferred the option with a strap without a buckle.
