The rubber was already torn when I open the box.

Aufbau sehr einfach, die Schrauben sind bereits in die Füße eingedreht (dachte nämlich zuerst auch die wurden nicht geliefert... 😅)Keyboardständer ist 80cm breit wenn ich die Höhe auf ~ 64cm einstelle, was für meine Keystation49 MK3 gerade noch schmal genug ist, um es draufzulegen und komfortabel zu spielen.Für schwererer Geräte könnte der Ständer schon etwas instabil werden, aber grundsätzlich sind die Standbeine breit genug und geben Stabilität/Rutschfestigkeit - reicht für mich zum Top-Preis 👍

I bought this for home use with my Alesis Q49 MIDI controller keyboard and it's pretty much the perfect size. You can move the four rubber grips on the top bars in towards the centre. The keyboard can sit between the grips, preventing it from moving, or on top of them, preventing it from sliding. With a little thought, the stand is simple to put together, though if you suffer from arthritis it might take several goes to unscrew the bolts then screw them back in once the feet and top bars are in place.When I first put it together the stand did sway around a little but I upended it and made sure the feet were as tight as possible, wiggling them as I used the allen key to make sure they bedded in as far as possible. Now it's as solid as you can expect on a living room carpet.With the height set midway (the third of 5 holes) it seems to be ideal for playing standing up, with the keys at 35" from the ground. On the lowest setting, it feels ideal for playing sitting on my rotary office chair, with the keys at 27" from the ground. The stand has only just arrived, though, so if it does get uncomfortable I'll come back and edit this review. The Q49 keyboard is 32" wide and it fits on the stand with about 1/2" to spare at either end. This could be useful information if you're thinking of using it with a different 49-key keyboard - one with less than full-sized keys, for example. The depth of the Q49 is a little under 7.5" and the stand is 13" deep, so this leaves about 3" in front of and behind the Q49. The next model up, the QX49, is 9" deep so, again, there's plenty of room.This is a very good stand for the price, in my opinion. But there is one drawback. As I understand it, if you want to fit an extension stand for a second keyboard you would need to remove the ends of the top bars in order to push the bottom of the extension into the holes. But the top bars of this stand seem to be solidly plugged with non-removable plastic caps. The rubber feet on the stand, however, are removable, so it might be possible to place the stand upside down, remove the two feet at the back and fit the extention that way. But then you'd lose some of the stability of the stand, and the rubber grips would no longer hold the keyboard in place as the feet don't slide in and out and can't substitute as grips. And, yes, I did check that I put the stand together the right way up with the long feet at the bottom and the shorter arms with the grips at the top.To be fair, it does say, "Keyboard extension arms cannot be added to this stands" [sic] on the product page, but I've only just seen this after a closer look. I wish that it had been in a more prominent place. However, as the stand is good value for the price, I've given it the full 5 stars.

Franchement pour le prix c'est top et stable

Parfait
