No, I would not recommend this.

Quit working less than two months in!

One morning it was just dead.. cleaned it, let it cool, still nothing. Just out of the blue — dead. Marinedepot customer service was no help either - they told me to contact the manufacturer — in Singapore??? I wrote it them, and only got silence back. $25 down the drain.
