Query: Ran hot, melted & destroyed batteries

Well I got this because I heard good things about it as well as I wanted the flexibility to charge 8 batteries at once.Unfortunately I got a defective one as after a couple of months it ran hot one day while charging 4 eneloope batteries and destroyed them. Luckily I never charge batteries while not being around, so I was able to avoid a fire.If you own one, keep any eye on it.
