I bought this cable to power small speakers from USB battery pack. Unfortunately polarity is wrong way around (+ inside, - outside) for them. With this price it's no big deal but it would be nice to have exact specifications on the product.
I've only briefly tried this steam cleaner and it seems that it's brilliant for cleaning some kind of dirt and useless for others. Anyway, I would recommend this since it's quite fun to use and will make your bathroom and kitchen much cleaner than you though would be possible.
