I order another machine back at the start of April but it still has not arrived. It is a more powerful professional machine to go with my licensing. I order this so at least something arrived. This supplier followed through on delivery. Though I can not say that about a supplier claiming to provide other. thank you for getting something here though not machine of choice purchased. That supplier still has no estimated time, as the time given came and went and still nothing. so this one gets you the order. one has to fill, empty fill and refill when using different handles and only one at a time.
