Works Perfectly
Only "issue" is that it takes a while to setup
I suggest you prepare the following
1) Cordless Drill with the correct HEX BIT (you will adjusting the fittings a lot)
2) Measuring Tape. This is the only way to get things aligned properly. Make sure each T-fitting is the same distance from the floor (for the left and right A stand) so you end up with a perfect stand
3) Bubble Level. Make sure all your horizontal tubes are level. Also when you are adjusting the holders, You can use the level to make sure the 2 holder arms are parallel. I used an iPhone App, but a bigger physical bubble level will be more useful
4) make sure you jam the fitting into the horizontal bar then u use the locking clamp to make sure it does not twist. Once you do one side, repeat on the other side. Make sure while u are jamming the opposite side, the original side does not pop up. I was lucky my 88 key piano did not drop down the next day. Again double check
