I have a friend who is in china atm and I've asked him to buy the WMO 5-pack for me (~13 USD!!). It looks original to me, here's the link (shortened): http://tinyurl.com/6c3brel

1. Is the WMO's sides similar to the IMO's? I bought the IMO once but I couldn't use it for long because the sides are shaped like /___\ so it slips off my fingers.

2. Is the WMO easy to lift up? I'm currently using a G1 copy (Logitech M100) and I'm quite happy with its shape \___/ but the buttons and sensor are crap.

Thanks a lot
