My first day out and the plate that's supposed to securely snap into place popped off without my noticing and was lost. This could have been my error, but I don't think so. Seems like a poor design. With the help of a little electrical tape it's now fully functional and I'm happy with it. It sits nice above the bicep and doesn't cut off circulation. Quick and easy in and out for changing tunes and snapping pics of the beauty all around.
