eTOMMENS power supply unit

[Croby80]

Hello to everybody, I'm looking for a good (but not expensive)  power supply unit for my personal laboratory and I'm observing the following model on aliexpress store:

https://it.aliexpress.com/item/1005001615696493.html?spm=a2g0o.cart.0.0.5a3d3c00R6iaCI&mp=1

it is a single channel 300W programmable power supply with a declared accurancy of 0,01mA for current and 0,1mV for voltage with capability to record and graphically visualize voltage current and power . It is possible to define 100groups of timed programmed steps and also to manage battery charge slopes. RS232, analog and USB interface are available (LAN optional) to be conneted to a PC to remotly control and to visualize V,I,P,R parameters. Sense compensation is another feature with a 4,3" rgb graphical display.  Price = 511euros.

Brand is AB-F but I suppose could be a rebrand for eTommens manufacturer: http://www.etommens.com/dgweb_content-847183.html

Anyone has experience with these devices?  Some expert could kindly give me his opinion?

(I attached datasheet of previous 5 digit version =0,1mA, 1mV)

Thank you
