Super fast shipping (EU warehouse), excellent packaging (original one). A small form factor switching mode PSU with lots of power and with excellent functions. The user interface is very intuitive, the supplied manual is hardly ever needed (maybe switching off the annoying beeping with long pressing OCP is the only exception). If it's not heavily loaded it's also completely silent. Some of the good functions: 1) It has hard on/off switch (so no active electronics is powered when switched off). 2) It has output switch (so when powered on it does not immediately outputs voltage, you can adjust first without unplugging). 3) It can work in both CV and CC mode (in which mode it drops voltage till current is decreased to the limit). 4) It has also OCP mode (in which case unlike in CC mode it switches off the output instead of reducing voltage). 5) It has good resolution and 2 memories. 6) It can be SW controlled (USB stick received with SW, I have not tried it). 7) It has USB charging output. 8) Cables (both power and USB) are reasonable length and quality. Being a switching mode PSU it has big spikes in the output though. The RMS value meets the spec, but as we know it tells just a small part of the story. Luckily it seems that the core of this is shared among several other products so the method described in the video "Getting rid of Excessive Switching Noise on the Longwei LW-K3010D Bench Supply" is also applicable here. In short: This is a very good feature packed and powerful PSU that has all relevant functions for a reasonable price and if needed can be modded to be even better (it won't be still a linear PSU though if you look for very low noise output).
