I don’t like them.
I needed a numpad to go with me TKL keyboard, because I occasionally do data entry. I picked up an Epomaker TH21 with yellow switches and I hated it. I’d naively thought “I’ll get a numpad from the same folks that made the keyboard that I love” and didn’t check the switches.
My keyboard (Ajazz k870t) has brown switches. They’re loud and bouncy and I love them.
If you’re expecting an experience like with blue or brown switches then you might be disappointed. Yellows are linear, so there’s no bump/click when the press registers.
I really like yellows for gaming, but if you’ll mostly be typing then you might prefer something else.
