FYI, I installed this yesterday. Very nice design and potentially great, needing 1 key improvement. Inexplicably it’s about 1.25 inches short and will slide back and forth when drawer is open. I solved this by adding double-sided tape (type with white foam layer inside) on the left / right sides below outside edges. And then I left the other side of tape backing on, so it slides smoothly and snuggly into place. This effectively keeps it from moving around, and it can be easily removed by sliding forward that 1 inch and lifting.
Also, it’s important to leave at least 2 Tesla cup holder dividers underneath, otherwise the tray sits down too low for the spring-loading balls to hold the Tesla drawer in mid position.
Overall, it’s great to have an easy access tray on top for items. The drink holders are narrow, but work fine for normal bottle of water and grande coffee cup.
