Sun CompanySun Company Digital Zipogage - Compact Zipperpull Digital Thermometer | for Skiing, Snowboarding, Cold-Weather Camping, Snowshoeing, or Any Outdoor Activity

This is my second Sun Zipogage digital thermometer. I got the first to mount on my bike handlebars so I could see what the temp was. I got this one for camping.I compared the readings of both Zipogages, and they are within 0.3 degrees. I also compared them to a a Sun glass thermometer and a indoor/outdoor digital thermometer. They all agreed, which I take to mean there is confidence in large numbers of agreement! (The Sun keychain glass thermometers were not great: both had the red line on the opposite side from Fahrenheit, and one of them was 4-5 degrees high. I recommend sticking with this digital gage.)PROSThis is easy to read, especially compared to the glass thermometers.It has an on/off switchThe battery seems to last a very long time. (I usually turn if off when not in use, but I have accidentally left it on for a week or more and it's still going strong.)CONSThe on/off switch is very easy to bump (but if you accidentally turn it on, no real worries because the battery should last for your entire camping trip and much more).It has no high/low memory settingIt costs three times what the glass keychain gages doWhen you take them outdoors, they are very slow to find the correct temperature. When I commute on my bike, it takes 15 minutes for the gage to reach what appears to be the outdoor temperature. But if you are, say, camping for a week and always leave it on, you should have few problems.

Here’s one for the record books: I sent one back to exchange for a new one thinking it was stuck on 72.5 degrees because the battery was dead. I had tried to get it going for 20 minutes, then my wife tried for 25 minutes, to no avail. Took the battery cover off, the plastic battery shield sticker off, took the battery in and out 10 times, but nothing.When the new one came I saw it was stuck on 72.5 degrees, too. I’m thinking, WTH?!? Sounded too far fetched to be on the exact same temp so I inspected it closer and there’s a thin plastic over the display screen that needs to be peeled off. We should’ve caught it but we didn’t, so I sent a perfectly good thermometer back. The directions said nothing about it and we both missed it. Sorry about that.I’ll come back in a month and review it further but I’ve checked it against two other thermometers and it has been exactly the same both times so it looks like a winner.

The big button is good for display on/off and a long press to switch between °F/°C. I like that is has a lower minimum than the other one I purchased. One concern is it seems the screen is shifted just a little to the right, the °F and the decimal very close to the edge with a large space for the 100s digit. No big deal really.I placed this in my refrigerator freezer along with two other brands/styles and all three were measuring the same temperature so that is reassuring. I really like the compactness of these units.Excellent customer service should you ever have a problem with it!

I thought this might be nice to take to the ice rinks. When I received it , the package instructions said to open the battery door and remove the battery insulator tab. There was no tab. Since it wouldn’t turn on. I replaced the battery, which allowed it to turn on. So this is an indicator that it was either returned and repackaged, or when it was assembled they left the tad out. After letting it sit on the end table it was more than five degrees off.

I received this and like other reviewers, peeled off the back sticker and opened the battery compartment in order to remove the "battery tab". Look very closely but there is definitely no tab to remove. Replace the cover, but the thermometer is clearly not working. Dead battery? No, says my trusty battery tester, the battery is very good. Repeat this process 2 more times, when to my surprise an invisibly clear ultra-thin plastic disk falls out of the battery compartment on the last try: the "battery tab" with no tab. So--if you can't get it working, take out the battery and turn the thermometer over and tap it to dislodge the invisible disc. Hope this helps.Also - it is measuring accurate within 1 degree, when compared to my Ecobee wall thermostat.

This thermometer reads one degree high consistently from freezing temperatures to the low 90s (low 30s C). That's not really an issue for me because it's linear, and I don't use this for any scientific purposes.Other than that, it simply works. I usually keep it hanging from a loop on my pack and look at it from time to time out of curiosity.It's extremely lightweight and I don't know how long the battery will last, but it's been going strong for the last nine months and doesn't show any signs of quitting.All in all, I think it's a great addition for those who care about temperature while they're out and about.

Compact, lightweight, digital, clips onto a backpack, easy to operate and read. Withheld one star for not being very accurate, something like +/- 2 degrees. But much more accurate than trying to read those mini-glass thermometers. Helps make good decisions and choices to know the (approximate) immediate temperature outdoors.

Reads high by 2.5 degrees F at 76 F. - should be good enough for most outdoor use. No night illumination. Quite light, easy to handle, easy to use. Battery installation is trial and error, but enough trial and it's in.
