It arrived

It arrived from an eBay seller. The loop at the end fell off in seconds but I've fixed it back on now. This didn't bode well. . .

I couldn't work out how to get into it as the top wouldn't come off and everything I turned and pulled didn't work and felt like it may break. I used a butter knife to prise it open but that didn't work, just damaged the casing.

I worked out (eventually) that pushing a tiny button on the end of it which I hadn't noticed made the top Spring off. Doh!

Clearly I've been working too hard!
