Positive experience with YLL customer service

Bought the YLL 3.0 from them, used daily for a few months, then it died on me, they sent me a replacement, which didn't work, but then they sent me ANOTHER replacement which worked and seems of better quality.

Every time I emailed them, they responded within an hour. They weren't combative or tripping about anything, I was expecting them to be way less helpful.

IK there's a ton of hate for this company, but buying directly from their website has been a positive experience for me.
