K&M 14020 Picco

I bought this as a space saving, lightweight keyboard seat and as such it works. It's also comfortable enough for a 3-hour gig. So far, so good.
Problem #1 is the chair to spindle screw. It has to be really, really, REALLY tightened in order to not come loose. When I switch from front keys to right keys, I move the stool and a number of times I ended up with just the seat in my hand. Hate to think of what might have happened.
Problem #2 is the height adjustment. In order to fit in my case, I have to push it all the way in (great that it fits!) and for playing I have to extend to hole #6. That's from my memory, I'm still figuring out where the seat's memory is supposed to be. The locking button gets stuck all the time, it's hard to find the right hole and when pushing it in it often shoots all the way in and the spindle can only be retrieved with a butter knife (so to speak).
Bottomline, it's what I need and as such content, but it's far from perfect.
