The stand is very stable and took only about 10 minutes to assemble. There two end pieces have two holes for synth legs to go through, but unfortunately they do not fit my Prophet 6 or OB-6, without leaving a 5 cm gap in front of the keys. Maybe i will drill the missing hole myself at some point. The paint was scratched and chipped off in some places before I event got it out of the box. Luckily not in very visible places, but none the less a bit disappointing.
I hope K&M will read this and improve the otherwise good product. The two minor issues I have experienced should be very easy to fix. I will recommend this stand for its great stability and ease of use, but at this price point the smaller details should also be OK.
