This is a well built sturdy and flexible stand that can carry many lighter keyboards or various devices, which can be organised in many ways. It is quite weird that there is no instruction manual to show you how to assemble the stand, which comes delivered in pieces. It is also weird that Jaspers website does not include any information as well. Assembly isn't particularly hard but I can recommend checking the pictures on Thomann website before starting.
More importantly, this stand has a few significant design problems:
1. The lowest section is reinforced with two aluminium tubes and two 60cm long supports (arms) for heavier keyboards. The first problem is that this only works for an extremely large keyboard that has a large depth like some organs or vintage synthesizers. If you, like me, have a 30kg stage piano with a depth of only 30 centimetres, the instrument will be practically standing on only one aluminium tube on a front side of the stand and its weight won't be equally distributed making the second aluminium tube on the back completely useless, which can cause a stage piano to slip down.
2. The second problem of the lowest section is that there are 60cm long supports (arms) included in the package. This means that if you want to put a heavier keyboard on them and distribute the weight equally over two aluminium tubes (front and back), you will need to put a keyboard at least 70 centimetres high (maybe even a bit more). If you wish to put the keyboard lower, you would need longer supports because those 60cm long supports that are included in the package won’t be able to reach the back aluminium tube and as a result, a stage piano would only stand on one aluminium tube (in front) and eventually slip down.
In some cases, like mine, this just does not work at all but some people might solve this problem by buying additional 70cm long supports that might fit the larger gap between two aluminium tubes caused by lower keyboard positioning.
3. Keyboard supports, which you may get in various lengths, have one limitation - once you attach them to the aluminium tube you can move them up-down (if you want to change the angle of the keyboard position) or left-right but you cannot move them more forward or backwards into the stand. If this was possible, it would eliminate problem 1 and 2 that I described.
If you have mainly lighter keyboards, up to 15kg, you won't have any problems and this stand will be perfect. However, heavy keyboards without a large depth will have their weight unevenly distributed when positioning them on the low section. Unfortunately, it is impossible to discover these problems unless you buy and try the stand by yourself. One can only hope that Jaspers makes a redesign of this stand.
