does your finger have to be warm

I don't know. Our fingers have always been at room temperature. I would ask the manufacturer. The reading is based on light absorption in specific wavelengths that is sensitive to the amount of oxygen saturation, but I don't think the literature explains if there is any temperature sensitivity.

I've found that with any pulse oximeter the finger has to be warm for it to get a reading. It probably has to do with circulation being decreased in cold temperatures. I have the person rub their hands together to warm up their fingers and that always seems to correct the error, whether it be blank lines or a "finger out" message.

Mine works best on clean, dry, warm fingers. Be shure to push the finger all the way In.

Yes it gets hot. Sometimes I can Pu with bare hands and other times need a hot pot mitt.

Normally yes - they are only warm to the touch. But if you leave them on too long they can get hot to the touch. Good luck!

Yes, I was concerned about that too, because it is my fingertips that get very cold. These liner heat very quickly also. I wear gloves over the top because these are just liners. I use them on my ATV for snowplowing, and they work perfect. This is my first season with them, and they have held up great so far.

oh no no, that's fancy! never heard of one that needs body heat. no this definitely doesn't need body heat it's just a normal stylus.

It gets warm, BUT not as hot as the cokingportion of the pot. I could pick it up without mitts.

Meh. I found the optimum temperature to cure this - in a reasonable time - very warm. The kind of very warm where you can still keep your fingers on it without too much discomfort. If it's too hot to keep your finger on for more than 3 seconds, your gonna melt the surrounding material. If you can control the heat gun to maintain that level of heat over a 15 to 20 minute period, then you're good. Patience is the key. The heat transfer tool?? A joke. You'd be there for a good 2 hours with it.

I'm not a kid :) but I love popscicles - and I would say no to the hands getting too cold. I do usually grab a paper towel but it doesn't last long enough for my hands to get cold.

When your fingertips are warm or normal body temp, then it is clear. So what ever color you have underneath will show up. When your fingertips are cold they change color to black or a darker shade of the color you have underneath. The first time I did it I had a hot pink color underneath. With two coats of the shade shifter on top, the color looked like a dark burgundy. The next time I did them I put three coats on and the color turned completely black. So yes, it does change color.

If your fingers get wet then these will just hold the moisture in. If they stay dry and/or you are wearing them under something then they should help keep your fingers warm.

No, no. the cup is not heat friendly to the hand. Not as well insulated as the storge cups

it gets slightly warm, but it's meant to stay cool. you can hold it without burning your fingers

yes it does get warm, I guess that says it is using a lot of power, the product works great!!

Well your in luck! it does NOT require body heat to work. Although the stylus is maybe a little over 2 inches so I'm not sure how functional it would be wearing bulky winter gloves! Have you thought about touch screen gloves?

this will happen if your fingers are too cold. try to warm your hand first, or try a different finger

Absolutely not...it feels slightly warmer than your body temperature but it is a soothing warmth. You will love it!

I can not give an exact temperature but it will burn your fingers through the glove that comes with it. It doesn't have a heat setting. Use with caution and never leave it unattended.
