### ⭐ Poor Quality Control
*by K***T on April 2, 2023*

I have always been a Big fan of BK Precision until now! I know it's been quite a bit since I bought this unit, but after retirement and getting settled in. started working on my electrical projects. "to me Amazon alwaysrushes the reviews". but now that I am using the power supply daily, the Current display would go Haywire!and with the time that has gone by, I know that support would be impossible. so I removed the Current PCB to have a look! Zero Quality Control!!!! I should have taking pictures, but you know how that goes. The PCB was covered in Debris, lot's of whiskers and old solder! Just Poor QA, was able to clean the PCB and seems to be working find now. But have lost all faith with BK Precision, was going to buy a BK LCR meterbut after seeing what I saw, will be looking at different units.
