Yes I have seen it work (many times) -- I have two of them in my trailer ( been there for about 4 years). I just installed two of them in my buddies trailer that lost a paint job, one rear fender, turn signals and many chrome pieces on his Screamineagle going to Daytona last year. I have hauled my bikes thousands of miles with them. My buddy just hauled two of his bikes to Minnesota and back with these in his trailer. I will GUARANTEE you that neither he or I would ever put our bikes in a trailer with out them again. NOTHING stays on your bike. There is a screw clamp that attaches to the bottom of your bike frame when outside of the trailer. You then drive into the trailer and the floor mounted assembly automatically clamps onto the bar. The only thing you have to do maually is shut off the ignition and get off of the bike, and close the door. To get bike off of the mount when unloading, you sit on the bike, push a lever with your foot to release the bar and back out of the trailer. When out of the trailer, you unscrew mounting bar from your bike and you are ready to ride. Takes less than 30 seconds to load or unload --- AND NO FREAKIN STRAPS TO SCREW WITH!!! IT IS NOT GOOD ON YOUR SUSPENSION TO HAVE IT STRAPPED DOWN FOR AN EXTENDED AMOUNT OF TIME, with this system the suspension is in its normal position. There is even a place on the assembly to put a padlock if security is a factor for you. It is virtually impossible for this system to fail. The system is stronger than the floor of your trailer. Life does not get any better than that.
