Are they Makita or look-a-likes? I've got a few of the 18v 3ah Makita kits and the batteries are great, like impish, I think I'd be cautious if they are copies tho.
Well if your buying them knowing there not genuine and you aint expecting them to be as long lasting as the real thing then at 65 notes for a pair it's gotta be worth a go, even if you only end up getting half the amount as the gens then they would still be a handy bit of kit i reckon mate..
