The delivery took place within a very short time. The mouth mirror looks very robust and 'professional' out - like at the dentist. Very important to note read at various 'predecessors': before applying a few seconds under keep warm water, then he does not fog. Magnification is OK (for what you see then (possibly in horror), the mirror can nix ;-) ...) - and you can see otherwise invisible areas (again: for what you see then (possibly in horror) ...).
