K&M 18952 Stacker BK for 18950

The quality of this stacker is noticeably good.

That being said, I only used it for my laptop.

A 20kg Moog One makes it wobble while playing. It doesn't look close to breaking or anything, but I wouldn't trust it with top-end devices, despite them weighing around 2/3 the supposed load capacity.

I like the quality of this product and found very straight forward to set up - once in place they are very stable and highly adjustable ..... to the point where you could find yourself struggling to get both arms lined up at the same angle when you tilt the arms .... would have been nice to have some indicators sketched onto the brackets to you can use that as a guide - However this is a small point as once set at your preferred angle you can leave them like that and simply stick them in your back along with the 18950 without having to alter :-)
