It is useful for packaged pantry items or kitchen tools. The medium is a much better fit for me, although I did see what other reviewers were saying about some bagginess in the material behind the knee. Half of other similar holders. Used these hook to make my curtain holders. However, I have yet to go to another carrier to see if it works on their network. Go buy the blue $25 reader/writer and takes 2 seconds to clone and copy code onto this fob. 5 depending on the brand, shoe style etc. As a side note, the AT2020 is another incredible deal, its very low priced compared to other professional microphones but it does not disappoint in sound quality. Es bonito y la talla se ajusta bien pero la pulsera del tobillo es muy pequeña I cannot walk barefoot comfortably but with these I can walk on them for a long time.
