I bought two sets of W708 Pro + WF01.
I am very pleased with the results after installing them in my cars.
The User Manual is rather reduced, but any questions I had were quickly answered by Carpuride, sometimes within minutes.
In my BMW I could not connect directly the WF01 to my reverse light: there is too much electronic circuitry in the car and the WF01 expects simply 0 or 12V, less than 11V won’t be accepted. I decided to install a dedicated switch in the midden console, and the corresponding wiring.
Besides this extra work, everything worked fine.
And direct shipment from Carpuride went also smooth.
