To start off I just want to say that this thing does fo its job. It feels great, too. Now for the griping bit. I opened the cup and lube poured out like thin maple syrup. Now I live in a fairly warm environment and who knows how long the cup sat on a delivery van so I can't fault tenga there. What I can fault them for is the thinness of the elastomer. I'm barely above average length but quite a bit girthier than your average American male. Upon insertion I was impressed for the first three strokes. Then I noticed a different, more foamy, feeling. I thought to myself, "Hmm. That isn't right." But I kept on because it wasn't painful or anything. Then things started to dry up very quickly. Almost like all of the lube had leaked out somewhere. I didn't have any on my hands so I did some investigating. I carefully extracted the "sleeve" and found a split running the entire length of the textured rubber. Now I'm going to err on the side of humble and say I doubt I was too thick to blow out the walls of something engineered to, quite literally, take a beating. I assume I got a bad sleeve that made it past QC. I just hope it was a single cup and not a bad batch.
