Not tested yet, but looks as good quality.
This voltage regulator unit arrived relatively, in about 3 weeks door to door. Seller send out my order right a way with out any delays. Unit performs as expected, easy to integrate in to existing PSU. Display is very bright and easy to read despite a small size. It looked much bigger on the pictures. Unit hold both modes CC and CV very well. So far no issues with this voltage regulator. The quality of assembly is excellent. No running flux, all components mounted exactly to their corresponding places on PCB. All an in all, I like this regulator a lot, considering ordering another one.
