I have a "no-name" version of the silicon case. I bought it to use as part of an armband, workout case and it works pretty well. It cost 10.00 from meritline.com. ( A search isn't coming up with it
) It came with the flip cover, which I don't use when I run and a belt clip, again never used. The lift up cover doesn't latch or catch in any way and is of a rigid scratch prone plastic.
I'm not sure I would like it as my only case, but with a little surgery on the back and a velcro arm band, it runs with me, several times a week.
