My history matches yours! I’m not as thrilled with the silicone, but I don’t mind it. It still feels a bit slippery but I’ve been dropping things lately regardless, so I just received the Native Union wrist strap.
https://www.nativeunion.com/products/city-grip. I did get mine thru Amazon (hard to beat accurate shipping and easy returns). They have a sling version too.
The design seems really smart and I had no trouble plugging in the charging card with it on It also comes with a standard cord for threading thru lanyard holes if your case has those.
The cord is substantial, but very comfortable because of that, and almost spongy due to the way it’s woven.
So hopefully this will help me with the silicone.
