Query: Don't buy

I bought this product and really enjoyed it for a month. Then it stopped working. The reason why? The battery in the remote died. And there's no way to turn on the unit without the remote. This is an inexcusable design flaw. Worse still, changing the battery in the remote is not simple. And the manual (as well as the on-line PDF manual) say nothing about changing the batter. I paid almost $100.00 for this piece of junk. Stay away.
