Nope, love it. I've done Char Sui Ribs in the slow cooker and they were delicious.

An extra step that I do at the end is pour the sauce into a 12" frying pan
over a high heat, add 1 tbs cornstarch, and reduce by a third to half (should only take 5-6 minutes).

Baste the ribs with the sauce and slide them under low broil for a 3-4 minutes,
flipping them halfway through.

Maybe things are different with a slow cooker but I use an air fryer like the chef in the video.
