I have the wheeldock version, and it took me 30 minutes in total to install it. About 25 minutes to figure out exactly where it goes, and then 5 minutes to actually install it.
I use it daily, in the garage at home, saves a lot of space, and when filling up the gas tank, also for any cleaning. Matter of fact, I rarely use my lift anymore just because I can get so much done with the center stand.
You shouldn't use it if your parking on anything other than flat surfaces, (at least I don't). It also is very handy on trips, providing equal easy access to everything on the bike, bags tour pak, etc.
If you let the owner at Wheel dock, know your interested, he normally will have a stand that has been returned that he'll sell at 20% off. Might have a scratch somewhere, but you'll never see it once it's installed.
