@Kev picked up a Metabo cordless fan last week in preparation for the summer, for anyone like us who has already invested in the batteries at $100 bucks it seemed like a really good buy.
First thoughts are, a really solid and a nice quality fan, very quite with 3 speeds and all metal construction apart from the fan blades.
I Had it running for about 4 hours on one 5.2 battery, but I can't remember now if the battery was fully charged so the test isn't scientific, I'll test again when the next heat wave hits.
It doesn't oscillate because of the design but can be wall mounted or connected to a tripod just like the Metabo cordless light which is also very good and has two light settings.
I haven't been able to locate the Metabo tripod for these yet, I have seen them on Youtube but not sure if they have imported the tripod into Aus and how much they will cost.
