I’ve had it for AGES. I agree that ads have been a bit much and many websites almost unusable without Origin. YT Premium though has been fairly solid with a couple hiccups.
Admittedly, I use YouTube as my primary source of entertainment. So the price is easily justified vs other services.
Sooooo depends on what you’re using them for. Very few shoes will hold up to retail work, for instance. So 3-6 months for one reviewer without context could be 2 years for you.
