Unfortunately there is a slight angle to this tower so my knees kept hitting on the way up. Facing the opposite direction helped but it felt less comfortable. The angle is the main reason I am giving this a low score. It's hard to see the angle from the picture however once I did my first pullup I was pretty disappointed.

Also I really like doing close-grip pullups, which I wasn't able to do using this tower. I thought the inside pullup grip would suffice, however its spread too far to get the effect I was looking for.

It did seem to be relatively solid, it just wasn't as functional as I thought it would be.

I took it down and got one of those over the doorway pullup bars instead.
