All Slow Cookers SUCK (almost)
Who wants to cook their food for 8 hours in some nonstick glaze/coating?
Even the ceramic pots generally have non-stick and theres very few on the market that dont.
The only one i can think of under £100 is the instant pot duo (which sucks on its slow cooker function and even on high setting only reaches dangerously low temp levels).
Slow cookers suck.
