The garmin clip I used on the back of my phone was from ebay seller "clipoo" and was $8 but is no longer being sold. It is very high quality and made from metal with 3m tape on the back. Before the Moto phone I used a big LG G4 phone and hit a big bump and the (detachable) phone back separated from the front and launched the phone into the air. The clip however stayed put with the phone back attached to my bars. If I was buying a clip I would get this or the one in the pic as it has a larger stick area than the other ones for sale. Note I roughed up the back of the phone with sandpaper so it adhered better (try doing this on an expensive iPhone!) . And after the LG episode I looked for a phone that does not have a detachable backface (hence the Moto E).
