I never had issues so far. The feet lift them maybe 0.05 inches from the groundIsn't like CDJs can overheat placed like that? (first pic)
You are right though that placing them up there is by far not ideal.
- It's too high for me - I can't work them without having my arms up
- they don't sit tight - they just lay on their bodys instead of the feet
- they're too long - I had to move the table like 7 inches away from the wall. The Vestax table wobbles like you're on a ship when I'm scratching
I though about getting a Spacetek double-arm but I find them very expensive. It could also be in the way of the platform on top of the table.
