I married this tray to my Putikeeg mirror finish paddle, and the combo works perfectly. (I reviewed the Putikeeg paddle separately.) This tray is well finished and comes with six very thin, rubber feet. The feet really stick to a smooth surface. My operating desk has a glass top, and the tray/paddle DO NOT move. Period. The magnetic feet on the Putikeeg paddle really lock onto this tray. If you want a stable platform for your Putikeeg key/paddle, this is the ticket. No doubt this tray would work equally well with any key or paddle having magnetic feet.
