###My review of the slim covers.
Yesterday was the first rimswapping event hosted by the austrianfairphoners. I had ordered some spare parts for on-site repairs/exchanges/tests and a lot of slim covers for everybody who wanted one.
The order arrived a few days before the event so I had some time to get to know the covers, fell in love with the white and turquoise ones and decided to keep them. 
More pics here.
Here is what I can say about the Slim Covers so far:
- The mechanism is really well done and taking the (back of the) cover off is now easier than ever. This nearly makes up for the lack of a transparent version as you can show everybody the insides of the FP2 in seconds.
- I didn’t experience the reboots issue as I switched Power and Camera buttons right away. It sure seems like it’s simply a mistake that the cover comes with the button that has a relief as the camera button. @Douwe did the tests you arranged bring any results?
- As expected the white cover gets dirty easily, but you can just remove it, wash it at the sink and put it back dry and squeaky clean.
- I believe lots of people will get more than one color so they can adjust the color according to their daily mood or outfit. The fact that there are 4 cover colers, 2 button colors but just one rim-color will probably result in some spare rims laying around at home. Let’s hope the rims are the parts of the cover that break the easiest!
- People at the event yesterday agree that Fairphone should release the design files of the slim Covers so people can print their own designs. The actual back-part of the cover is probably easily printable and if done in good quality can work together with the official rim and buttons. ( @Douwe what do you think? )
- Maybe a artisanally talented person could try to repurpose a regular cover’s plastic part as a slim cover’s back-part. → DIY Transparent Slim Covers!
All in all I believe the slim covers are a great upgrade, will hopefully be even more personalizable in the future and truly incorporate FP’s message:
