IF you still have the link, would PM me with it please?
I'm curious about the wire as it looks like it's either very thin wire, or flat wire.
IF it is flat wire, then it is not worth the time due to the same issues using flat wire that even the guru's from years past on here have had.
IF it is very thin wire, then the voltage will be interesting.
I'm also betting the 2-stage is an external step not internal to this built unit.
@MattM I've ordered from Ali--express for years now and have always gotten what I ordered.
However, I always read and copy the description of the stuff I'm ordering and expect an answer from the seller long before I place an order.
Cheers
