Fatal design flaw. Product failure occurred at the multiple locations due to a lack of material thickness for adjusting screws. The material thickness will barely engage one or two threads and the adjuster screw diameter is around 1/4". I don't remember the general rule for minimum material thickness ratio to screw diameter, but this product doesn't meet it. Not anywhere near it.
My wife purchased this tray to use in her salon and it fell apart in a matter of weeks. We just tried to return the product, but apparently we waited too long because the vendor rejected our return request. I think the 30 day return policy for a refund should tell you all you need to know about how long they expect the product to last.
