I ordered this chinning bar several weeks ago from Karate Depot. The item first showed as being on back order...after I had paid...I figured I was in for a long wait. Wrong! The back order took 0 time, and I had my bar w/in 5 days of ordering! Very nice! The unit itself is very easy to assemble, and took all of 5 minutes. It works superbly as a push-up bar...I like using it WAY better than my push-up handle things. I weigh ~240 lbs., so I was nervous about chinning...but it works just fine. Other reviews indicated that the no-slip strip leaves a black mark above your door...mine is up against a red paint, and I have not noticed any such effect so far. This is such a simple item, so there isn't much that could be wrong with it...that being said, it works exactly as it is supposed to...unless you weigh 300 lbs, I highly doubt you will have any issues with this bar what-so-ever. Combine that with good price, low/prompt shipping from Karate Depot, and you get yourself an easy as pie 5 stars! People who rate it less do so simply because they dislike doing chin-ups, not because the bar didn't work perfectly!!!
