Use the right screws!

I have one suggestion for the new owners:

Please switch to proper fasteners for everything. You should never be using countersunk fasteners in things that aren't countersunk. I've had to do major restoration on the bathroom wall because someone used countersunk fasteners there. I'm doing more work on the air conditioner shroud because of the fasteners that have a slight countersink there.

My wife said it well when she looked at things (she has laboratory failure analysis experience): The TM design is sound, but the execution leaves a bit to be desired. Don't forget the tiny things like using the correct screws!
