I bought the VS-88B bundled with the VSIQ-200B. Having used the excellent Ultimate Apex (with 3 tiers) for many years I thought this stand would be at least as good when I cut down to two keyboards.
Unfortunately this iwas not the case: there is so much lateral movement that it's almost impossible to play the top keyboard. I have a Korg Kronos 2 on the upper tier weighing 46lbs (well within the maximum recommended load of 50lbs). At the price, I was expecting a far more stable stand.
Additionally, the 200B does not fit in the bag supplied, and whilst the 88B folds down neatly to fit in the bag, with the clamps for the upper tier fitted, it won't fold down, so the clamps have to be removed every time and left loose in the bag. All in all, this was a very disappointing purchase.
