Don't believe it - it's NOT EASY....POOR DESIGN
Waste of money! Looks clever, but a nightmare to apply to the sheet itself. Worked for 2 hours (with tools) to very poor grip. 'Garter' rubber button will manage to punch thru clip eventually - but good luck locking in place. POOR DESIGN. Used reg fitted sheet, but end up fighting with the sheet elastic in order to prevent wrinkles - god help you if that happens as the margin between rubber part of garter and metal clip is completely unrealistic. Unless you have 4 incredibly strong hands - or some magic tool they forgot to provide - just try another product, but save yourself the frustration. Regular garters are a breeze - these are not your regular garter clips!! Did I mention it was POOR DESIGN?
