After three weeks of continuous use, I am of the functionality of the Bluelounge Kickflip still enthusiastic. Just writing longer texts, I find it much easier by the now more ergonomic laptop position. Visually, the kickflip on the underside of the MacBook is completely unremarkable, unless the good piece is turned around.
The biggest shortcoming that I noticed that mediocre liability which provides the bonding surface is. So the Kickflip falls about once a week now and must be re-attached.
If the bonding surface is contaminated with hair again, this is easy to clean with a lint roller out of the range of Swedish furniture.
