It's easy to attach to the PW with a coin but no opening for PW' battery replacement, you need to detach it for that job. There is another design on the market with battery opening (I will look for and post the link)
Bunjie can be replaced with the similar type manually. There are two simple knots at the ends.
Oh now someone speaks up about a different kind, AFTER Ive placed my order and its shipped! Stil interested to know about it though.
Do you think this is a problem? One would not be changing the batteries too often ~ I suspect but don't know.

Yea Im not really worried too much about that issue as the batteries last a long time in the PWs.
