    Great, but screen protector left residue that I can’t get off
    I really like the looks and size of this power supply. The buttons and knobs are all tactile and work nicely. I would have given it 5 stars except that the screen protector left behind a bunch of residue that I have tried to clean off, but can’t. Luckily it doesn’t affect the display very much. I’ve never seen this before and honestly I expected a little better.
