Nothing can be said about the machine ... it does what it needs to do. The manual is somewhat lacking, but someone with a bit of technical knowledge understands the explanation. The delivery ... that's something that seriously needs to be worked on. It's a cumbersome process ... ordering, paying, delivering to a depot. After that, you have to get in touch to find out the delivery date. I didn't even trust the thing in the depot ... but ... everything turned out fine. Maybe that's the way VEVOR operates, but not through here.
