Finn,
Never heard of a SuxiDi brand either. The popularity of the original, authentic Yong Heng, made by the YONGYIHENG Pneumatic Company, made many manufacturers in China jump on the bandwagon. Apparently, copyright infringement is not a thing in China, so it's the Wild West when it comes to copying anything to look like an authentic Yong Heng. Problem is consumer doesn't know if corners have been cut internally until it's too late. I can only say one thing for certain, best-homepro sold me, and many others, real, authentic Yong Hengs, at a fair price, no tax, free shipping. Any purchase, other than thru eBay's best-homepro, you're on your own. If you must purchase thru Amazon, then pick one and roll the dice, I wish you the best of luck, WM
