Product review (2 stars): Beauty is skin deep
It looks pretty. If it worked as nice as it looked I'd give it five stars. But of the two I ordered, one was totally dented on two sides, another came intact but had a control panel that didn't work properly. The instructions are also pretty bad, they have pictures of multiple different control panels and don't tell you how they all work.

Both units I experienced did not have anywhere near the 870CFM was listed. (The blower might be 870cfm, but there isn't 870cfm worth of suction on the bottom). One had a fan that rattled a lot. I didn't have a sound meter but neither sounded like they were 65db, except when they were off.

I've bought cheap Chinese knock-offs on aliexpress before that were good quality, but this is not one of those. Avoid it, or at least only buy the ones on Prime and check it completely as soon as it arrives so you can return it when it doesn't meet your needs.
