## Customer Reviews

### ⭐⭐⭐⭐⭐ Warm or Cool how do you like it
*by F***L on December 25, 2013*

I need to be warm in bed. My feet where ice cubes. I had experienced a hot bed in the VA heated water circulated in mattress. Wonderful. This is very similar without any electromagnetic radiation, which all other electric blankets do have. If you are warm and want to cool down this mattress does that too, just turn off the heater and the mattress cools. Wonderful warm sleep each night for me. Fast free shipping YES!

### ⭐⭐⭐ Nice and warm with a caveat.
*by Y***E on December 26, 2013*

My wife suffers from insufficient circulation problems.We needed a heated pad, but we are sensitive to electric field, or wave (what ever it's called).So it seemed like a perfect item for us. No harmful electric waves but warmth at night.The Good:1. Warmth: It can be controlled from 30 degrees Celsius to 60 degrees. I usually leave it at 30 and it still is very warm enough through the night even during 20 degree temperatures outside.2. Firmness: Our backs are very problem prone. This pad, however, feels just firm enough. I don't know if it's the firmness, warmth or both, but our back pain has dissipated after using this pad.3. Easy to setup: Plug in four plastic hoses to the unit and just pour in enough water until it beeps.4. Twin zone control: You can supposedly control temperatures for the two of you separately. However, there's a small problem described below.The Bad:1. This boasts of, 'No harmful electric wave', but I am suspicious of the claim. I'm not definite if it's the electric wave that causing it, but after using this pad we are experiencing puffy face and some mild headaches. It seems it's not much better than electric blankets or pads when it comes to electric wave. Took two stars off of the ratings because of this critical aspect.2. Twin zone control: It seems when you set different temps to the two zones, it doesn't work quite like you would suppose. It seems the side with the tubing always gets warm even if you set the temp lower on that side. So I would suggest the person who needs it warmer sleep on the right side of the pad.We're in between a rock and a hard place. If we use the pad, it causes some discomforts, not to mention who know what side-effects it may have on us internally. If we stop using it, we're back to back pains and other maladies.I was hoping for a true no-side effect product, but unfortunately for us, it is definitely showing some side-effects for us. We're going to look for some ways to block out electric wave if such things exist.

### ⭐⭐⭐⭐ Great solution to electrical heating mat issues!
*by C***E on November 4, 2014*

This mat far exceeded my expectations. I had used one of these when I was staying in Korea, but the quality of this particular one is far better. The materials used for the mats, tubes, and boiler are quite nice. The zone control and timing options work as they are supposed to. The only thing I was they would have done differently was to make the materials a little more pliable. Currently, I use the mat on top of my bed and it bends at the edges when I don't lay flat on my back. It doesn't affect the functionality, but it can make it uncomfortable to sleep on somewhat. Overall, this is a great product with a great vendor. Instructions are in English, even though the grammar is not particularly perfect. Very happy with my purchase!
