If you find yourself ever lucky enough to need to hold 3 keyboards on your stand, then the additional arms make this one of the best 3 tiered stands available today. However, if you are out gigging regularly then you will likely find the fact they do not fold into the stand along with the other two, a little annoying as they need to be fitted and removed each time you set up and pack down. It would be better if the access to the grooves the arms fit into was easier. Unfortunately you have to unscrew 6 screws or so to remove the top piece. The alternative(Which is what I do) is to leave just 1 screw in place and rotate the top each time. I have had no problems with it this far and as I said at the start, I still think this is one of the best stands offering the option for an extra tier through use of these additional arms.
