There are very good things about the module: premium finish and aspect / very small yet visible display and easy to push buttons. There is also bad: too complicated menu, with absurd abbreviations and the lack of any documentation with product, also nothing clear and complete on the internet. Simpler would be better. Furthermore the Rsense for the current is SMD - it will blow if load short-circuited since there are big capacitors that would discharge without limitation...They should use wire resistor. While testing, efficiency is acceptable but far from great, ergonomy exactly the same. The unit I have received would only switch on the load up to 26-28V, with bigger voltage it would get into some protection (but none was active!?). Probably a bad capacitor, especially since the problem went away by itself after some use, probably repolarisation of capacitor occurred.
