This is pretty good. I feel like the price is in the right range for the quality. Adds the very useful functionality of having notes right beside the visual timer. The whiteboard size feels about right for best convenience. If they made a second version, wouldn't mind an option that's got an extra inch or two in each direction-- but since there's only one I think they picked a good size.
Instead of friction-fitting (like the rubbery "Protect Cases"), the timer sets back into a space with grooves for the feet. This makes it much easier to slide in/out of the whiteboard. Because of the slant of the board, the timer is also slanted backward. This helps the timer stay in, and it's enough of an angle that you could bump/jostle this without separating them. However, if the board tips forward onto its face, the timer would slide out when you pick it up. (Make sense?) Not an issue for my current usecase, but worth being aware of before purchase-- especially if you're getting it for a kid/classroom.
Really, it's a decent design and I don't have specific suggestions for improvement other than making the whiteboard feet grippier; it likes to slide around on glossy surfaces (think countertop, dining table, desk) a bit more than I'd prefer. The mediocre grip does make it harder to knock over but probably easier to skitter away and slide off a table...so pro/con.
