Crock-Pot slow cookers too hot on "Low"

I have the white round version, approx. 5.5 qts IIRC. I've had this one for 3 years now and I use it mostly between Sept-Mar when the colder weather calls for comfort foods like soups, stews, etc.

I find even when on Low, the heat is still rather high and brings liquids to a steady if very gentle BOIL after about 3 hrs. Now since all dishes I make in this take at least 4-5 hours, they aren't all that affected since I need to cook them down anyway (meats).

But my perusal of online reviews of many Crock-Pot models seem to tell me CP products seem to generally go too hot on Low.

Is this the case with your Crock-Pot branded slow cookers ? If I were to buy another, what brand(s) are good alternatives ? Thanks in advance.
