This is a solidly built product that works well. The biggest "out of the box" negative is that the operating instructions lack sufficient detail regarding settings to use for various applications. Most disturbing however was that I could not read the glass oil level gauge when I opened the back to add oil, as all YouTube videos about the Vevor emphasize they are shipped with little or no oil and therefore a small bottle of oil is provided in the packaging. The glass level did not indicate any oil in the reservoir at all. I even tipped the machine back and forth to see if the oil was just too clear to show up on the glass. Anyway, I ended up putting in half the bottle (still no reading on the glass gauge) and ended up adding too much oil to the reservoir which caused it to overflow when I used it, coating the insides and making a mess to clean up after my first usage.
