Just saw it, thinking of buying it myself. Its reviews look good its a good brand just make sure you don't lock it while cooking or the glass can shatter. Really though its hard to buy a bad slow cooker. I'm sure its fine.
Also if you need a massive slow cooker for 5$ more
I use this slow cooker [link]
I've done 72 hour short ribs and they were fine, my friend has a vacuum sealer that we used for that, but normally I just use a normal freezer bag and try to get all the air out by putting it under water.
I like the 8 quart slow cooker in Amazon. I think I'm getting that one for the price.
