However, I have my GST 90 E pack almost in cotton wool so that it stays that way. Fastening system is a joke in my eyes. This was probably deliberately chosen so that we buy more always pretty. Yes it costs just over 1 per part (how much should cost 4 qcm plastic too?), Which makes it, in my eyes but not better.
The operation itself is OK, but you should not expect miracles. As a Mitrezensent already wrote, the choice of the sheet decisively.
