That's a very good idea. It doesn't matter what case you use and it doesn't rely on adhesive, it just fits snugly between your phone and the case. A small loop protruding at the bottom does not interfere with charging or using the connector. The strap, which can be attached to the loop, is strong and reliable, easily adjustable in length, which allows it to be worn both on the neck and over the shoulder, and is also easy to remove. The only thing that bothers me a bit is the fabric loop. This is a soft, flat satin fabric and I have no idea how durable it will be over time. But right now I'm VERY happy, that's exactly what I wanted.
