I actually bought one of the fire maple 'lightweight' titanium stoves in the end. Opened it up and thought it felt a little heavy. Low and behold it wasn't the 48g as stated but a rather chunky 70g. This was actually stated in the instructions as well, plus I weighed it.
I'm assuming I obviously have a duff. Asked for a refund etc (from eBay). Who picked one up that was the actual 48g?
