I had been looking for a tray this shape for a while, but I just could not justify the expense of them. Then I discovered this one by Thomann for a fraction of the price.
It does exactly the same as the more expensive trays. I've already used it 3 times in a month in orchestral gigs. It's also just the right size for storing tambourines, bass drum beaters, bass bows for vibes, etc.
The tray is really well made, easy to transport, easy to assemble (the memory lock also helps), and the fabric material feels good quality. Double braced legs help with stability too.
A great product all round.
