Sun Company Slip-on Wrist Thermometer - Easy-to-Read Dial Thermometer for Watch Band or Paracord Survival Bracelet

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.

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.

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.

Good customer service

Great concept that fails in execution. This item is well made. It functions very well... so long as you don't actually wear it on your watch strap. Doing so causes the thermometer to record your body heat, not ambient temperature. Needs a case that doesn't transfer heat but lets the gauge work off of the air. Will now secure it to a zipper pull instead which isn't what I bought it for. UPDATE: Today (18Mar) I received an unsolicited offer to refund the purchase of my thermometer. How absolutely cool is that? I turned it down because I found an alternative way to use it and it's working for me. But, just the idea that such an offer was made tells you a whole lot about the company. And it's good.

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

Perfect little thermometer- fits a watch band securely-24mm-easy to read!

Well I just got this so placing initial thoughts. I purchased this for my I need to unplug days and temporarily placed it on my miband 4 watch band. Which... It's very snug on. That's not bad, it seems to stay in place, but was some work to get on. My first two thoughts were #1 I really wish I could rotate the head 90 degrees. #2 within 10 minutes of placing on my wrist band it's raised almost 10 degrees. I'm not sure that bracelet I plan on using it with, will offer any better body heat protection for it...might have to play with that see if I can get a more accurate reading, before placing it on my watch band it was in line with other thermometers I had in the house. I wasn't expecting perfect accuracy, but at now about 15 degrees F it's pretty much useless. I'll have to figure out something else. from other reviews it sounds like the manufacturer knows about the defect and is not interested in making it right. I'll update if I find a way to get it to read more accurately.
