The plastic ones that come with the 8700c are terrible, and the leather ones with the stretchy sides wear out way too fast (the stretchy part loses it tension and the phone is no longer secure). It's time for a new one.
Can anybody recommend a good holster with a magnet that works well, preferably with a closing flap?
