Did you not just read what I just wrote???...My center stand works, and still does stand up to the extra weight that I have put upon it for 5 years now...80 to 90 pounds worth...There are many different ones on the market but I specifically linked to only one, The one that I know will work...I had those other so called center stands that don't stand up, I found through trial and error which one WILL work over the long haul and is still working 5 years later.
By all means, post your experiences with center stands and make sure to include links of those that DON'T work to back up your experiences with them.
