Sun Company Slip-on Wrist Thermometer

Bought this to go with my dive watch. I've read on a couple of posts here that it didn't work at all, right out of the package. So, when I received it a couple of hours ago, I immediately put it in the fridge for an hour, then the freezer for an hour. It worked. It wasn't digital accurate but close enough to 42F and 3F for my satisfaction. It will pick up your body heat. For me, this isn't much of a problem as it'll be outside of a wetsuit or mounted on my console. The only drawback is that the face isn't recessed and will undoubtedly become scratched or damaged with use.

The temperature displayed shows 60F outside when the temperature is actually 46F. Inside home it shows 90F when the actual temperature is 69F. This product is not accurate.

It is a great on the go thermometer that is easy to read and, relatively, accurate. As others have noted, it does pick up body heat on watch band. Not a big surprise considering what it is. Off watch band, it has similar accuracy as the general use thermometers I picked up from my local hardware store. I took off a star because the degree markers don't have luminescence (glow in the dark) so night time use is questionable.

Good customer service

Fits on my Swatch Moonwatch band perfectly. However, it is about five degrees off sitting in my office due it it picking up my body heat. I tested it by taking it off and setting it aside for 20 minutes and reconding the temperature, then putting it back on my watch and re-recording the temperature after another 20 minutes. It off by 5-8 degrees (I can't put a exact number on it because it only has marks for every 5 degrees) on my wrist compared to ambient room temerature. If you're okay with this, then this product is a good deal.

I actually got this not for my wrist. It's aways annoyed me that my car doesn't have a temperature display in it. This little Guage is perfect! A piece of two sided tape and now it's on the edge of my rear view mirror. Seems very accurate and I'm glad to have it.

Temperature at a glance. I have it on my NATO watchband. Perfect!

It doesn't appear to work. It said it was 80F in my 65 degree room and outside in 75F weather it reads 85F. I took it off my watch and put it under an ice pack for a few minutes. Apparently my ice pack freezes at 80F. I bought it because it claimed to be able to pick up the temperature in only a second but maybe they just used some misleading wording to mean you can read it in one second. Either way, it doesn't appear to work at all. I took it off my watch thinking the watch band was making it warmer. I'll see if it changes anything.
