I have had an Apex since day 1...that's a long long time..It [actually two] has served me well..I broke the mic boom mount[user error] once, and twice had to retrieve the bars in storage[with a slight modification this was corrected]..
It has never falling over or lost a keyboard...I have used it with two and three boards..
Warranty is absolutely the best of any product I can think of....and not just the music business..20 years and they still warrant the Apex..parts are shipped overnite..
You guys are missing the boat if you are not using an Ultimate Support product..

I also use A double braced X stand {On Stage, that's the brand}, with a mic boom attached..both of the keyboard stands work well, and support the keyboards with stability...
When I notice any bounce it is always the stage and not the stands..
