RD Tech suggested I open a dispute on AliExpress. AliExpress responded to the dispute in less than one day. AliExpress shipping accepted responsibility.
RD6006 feedback:
good item, it performs well, constant voltage and constant current output, and the WiFi board can work normally, it is worthy to order one, waiting for higher current version https://www.aliexpress.com/item/4000282551930.html
I’m terrible at metalworking. I smashed the bent case into shape using a 7kg barbell and a block of wood. Yes, I hit it with a barbell.
The bent case works better than I though it could. It looks 2nd quality. I will use the new case when it arrives and save the first case for parts or a 2nd power supply.
if you want to reshape the case, you need a hammer to hit the curved place gently, the case material is soft. and waiting for your test, you can contact me if you have any questions when using it, and I cannot see the picture because I cannot access the picture link :person_facepalming:
customer feedback
[In general, the product RD6006 turned out very cool, the control is done intuitively understandable, in 5/7 minutes you can completely understand it, collected qualitatively, does not overheat even when working on Max currents with low voltage(
[Fast delivery and great packaging. The housing is made to a good standard, all parts needed are included. The photos also show the packaging of the RD6006 itself which is obviously not included with this housing.]
This is a very interesting design. I am mostly interested in Constant Current mode and would like to know how fast does the circuit switches from Constant Voltage to Constant Current. In other words, what surge current must I expect on the output if I connect a sensitive circuit to it. Are there large capacitors directly connected to the output?
Thank you

RD6006 USB WiFi DC - DC Voltage current Step-down Power Supply
[excellent product!!! very well packaged(well packaged for rude delivery, we both don't want to see a broken device, it is a waste of time and money)] https://www.aliexpress.com/item/4000282551930.html
This is a very interesting item.
I’m mainly interested in the graphical monitoring of voltage and current like other more famous DMMs.
Very interesting software for PC …
Can you expect a version with 3.5 “or 4.2” LCD display ?
(I hope he will arrive soon)
and any improvement in voltage and current monitoring?
It works very well both in the laboratory and in the assembly line.
now I am testing one in my laboratory and 4 in assembly line …
Next day I post some other information about my experience with RD6006-W
