Bests & Worsts Reviews from Amazon

I loved my old crockpot so I was very surprised to get this and hate it. I read the reviews of the pot runnin too hot but I’m having the exact opposite problem- this does not get my food done. I’ve always been able to put a roast in the crockpot and have it done in 8 hours. I e tried 5 different roasts in this one at least and none of them are getting done- even at 10 hours on low. Today I put one in on high since I’m home all day and 5 hours in and it’s not even close to being tender. So disappointing.
