Don't get me wrong, the board got here on a Monday even though I ordered it at 17:00 on a Sunday (impressive!) however the board itself has a few issues.
It's great for:
Placing hot things on it
It's not great for:
Cutting. Due to the ridges on the glass you can't get a clean cut through a tomato for instance, you can't get that last bit that connects the two side of the tomato together as it's down one of these ridges, same for any 'soft' vegetable or fruit. It's fine for potatoes, onions, other 'hard' fruit/vegetables.
So, in my opinion, the board doesn't quite cut it.
