It didn't last more than one work out before the Velcro strip came off the arm now it's totally useless even though it fits the iPhone perfectly it didn't last. Plus shipping took so long t that I figured you just get what you pay for
Works well and fits my phone. However, the strap is difficult to engage with just the one free arm. I've taken to putting the strap through first and attaching it to the velcro, then sliding it up my arm already closed, then tightening it at the top. This is awkward. It would be easier to just connect it at the right part of the arm in the first place.
