When you inquire to the manufacturer, the delivery date is one week? There is Monotaro sending out on the same day! The product is a maker's thing and the sound is quiet and good things. The broken old type was operating for 10 years under a very bad usage environment. I think that it is very good.
It is compact and lightweight, easy to install, can be used at 100 V, the air volume was sufficient, in addition, the vibration of the thing that is available for business use, the operation sound is quiet.
