This works great and holds a charge for a very long time. The motor is a little loud, but not bothersome while operating it. I haven't tried it on water yet so I can't address that aspect of its performance. Wal-Mart had the best price on the web I could find and I always do a lot of price comparisons prior to purchase. I highly recommend it for home, car, and shop. Very satisfied so far.
