For what it's worth I've bought two Teco VFDs from emotorsdirect.ca and have had excellent experience both times.
I could not imagine the frustration of waiting for two months and then have the thing be DOA.
The Teco VFDs are a little out of my price tolerance and I don't really want to deal with wiring pots and switches.
The question now is "was the shipping fiasco a trend for things coming out of China now or the fault of the seller?". The silly thing was returned 4 times to the seller due to some kind of security check failure what ever that means. The same thing started happening with the replacement VFD so I pulled the plug. Probably should have pulled the plug on the initial order after the second return. Lesson learned.
I asked one of the AliExpress sellers if they would send me an English manual for my current VFD. He said they would but I haven't seen it yet. If I can get this thing to reverse from the key pad or even a switch I'd be set.
