A built-in silencer and insulation around the motor make for quiet operation.

I used the National for a few days, but it started to leak and then started to leak. I’m going to use this one again. They look and feel the same, they work the same, and most importantly, you can buy five of these for the price of the National. So, if this one lasts half as long as the National (so far, this has twice as many hours on it), you’ll still be ahead.
I only gave it four stars because it leaks air inside, but the $250 National does the same thing.
