well worth the money.
We bought a Queen sized mattress warmer from Navien, because there was no Cal King that I could find. It works perfectly. I am amazed at the engineering and care that went into this product. It is made to reflect quality, long term use and pride in product. The temp goes to 98 degrees or so, but you can bump it up. I find that 95 degrees warming the bed for three hours is plenty. It's just comfortable, not too hot. and if you like, you can leave it on all night on that or a lower setting. I LOVE this bed warmer. I can't say enough good about it. The instructions come in Korean and in English and are clear. and is IS dual in spite of only one warming unit.You can choose different temps for each side. There are lots of safety measures built in, for the unit and for people. I put the mat under a wool mattress pad that is also excellent. They work together really well.https://www.amazon.com/gp/product/B000GBA95O/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

You can feel the hoses under your bed sheets!
This product is junk. It is a large rubber mat with lots of rubber hoses. Then the whole thing is inside a rough textile case. Unless you are used to sleeping in a lumpy bed you could not possibly enjoy this.Further I returned it unused for a refund in original packaging as I received it. They still charged a 20% restocking fee. Clearly this is a sign the manufacture doesn’t stand behind their product. Other companies like Eight Sleep offer a free no hassle return process. I bought an Eight Sleep mattress cover in the end because it is simply better in every way.

Absolutely loving this product
The only thing I look forward to on cold nights. Unlike other heated blankets or heating pads, this won't give you headaches nor the puffy face in the morning.I would recommend this to anyone. :)One thing to note: It won't work with distilled water. Try using drinking water instead.

Worth every penny
Worth every penny. This is real good quality. I like that it is based on waster so you don't sleep under electromagnetic environment.
