I've had three different Chinese devices and have had varied experiences. One was a steel cage type, chrome plated over cheap metal. Upon arrival, the plating was chipping off, lots of dangerous, sharp flacks. Negative feedback to the seller, and I tossed it. I do have a China knock off, black CB6000S that I love, very sturdy, no breakage. My favorite, a stainless steel tube type, is shown in my pic album. It had a cage type extension at the tip, but I didn't fill it up, penis too short, so I hack sawed it off, filed it down, and love how it now exposes, displays my cock head. Comfortable, too.
