I purchased this charger for my husband in June 2011. He used it once and it worked fine. He used it again two months later in August, and it started smoking when plugged in! He moved it to a different outlet and again it started smoking and he could smell it burning. I'm just glad that he didn't plug it in in the basement and leave it there - it could have burned our house down.Do not put your family at risk with this product! Unfortunately I only had 1 month to return it and I didn't know that it was defective until I'd had it for 2 months, so I'm out $20.
