I also have ordered the one from aliexpress (http://www.aliexpress.com/snapshot/211496346.html
), I bought two pieces for 8,20$ piece. Hope I'll be a little more lucky with the sleep function, or else I just need to wait for it to autosleep. I'm also waiting for the PW to arrive.
Do you guys think there is a way to improve the speep function, perhaps change the magnet?
