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

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.

Easy one button function. I like...

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.) PROS This is easy to read, especially compared to the glass thermometers. It has an on/off switch The 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.) CONS The 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 setting It costs three times what the glass keychain gages do When 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.

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.

I threw this thermometer in the trash. When compared to a reading on a trusted thermometer, this device was ALWAY off by at least 4 degrees. Since it was either plus or minus four degrees, I asked myself, why would I want this on a hiking or biking trip. Like I said - I threw it in the trash. The experience was made especially aggravating since there was a slip of paper in the packaging saying it was inspected for accuracy by someone. DO NOT BUY THIS.

Works well and accurate. Wish and needs a back light.

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!

Bought used but like new. Expected package to be opened but they left it on so the batter has been running the whole time. They could have turned it off at least.

Ce petit thermomètre est facile à utiliser. Il donne des lectures précises et je le trouve pratique car il donne des mesures dans une large gamme de températures. Je l'accroche à une fermeture Éclair de mon anorak ou de mon sac à dos lors de mes randonnées ou lors de mes journées de ski. Je l'utilise aussi dans ma serre pour vérifier s'il ne fait pas trop chaud ou trop froid pour mes plantes. Je m'en sers aussi pour mesurer la température du réfrigérateur, etc. Je l'amène partout sur le terrain. Je l'ai depuis presque 1 an et il n'est pas abîmé. Il est encore comme neuf.

Ho acquistato questo termometro per utilizzarlo durante le mie uscite in bicicletta. I valori delle temperature misurate sono corrette ed allineate con gli altri termometri in mio possesso. Inoltre ho inserito il termometro, dopo averlo protetto con una bustina di celofan, in acqua e ghiaccio per qualche minuto ed il valore evidenziato è stato di 0°C che è la temperatura di passaggio dell'acqua dallo stato liquido a quello solido. Quindi questo termometro è perfettamente tarato. Lo consiglio.

Funciona muy bien, es muy claro de leer, pequeño para llevar y más o menos preciso.

Muy ligero, no pesa muy buen tamaño, buena presentación. Confisble

J'ai acheté ce thermomètre en octobre 2022 (22,5€ à l'époque), il est toujours fonctionnel, j'ai changé la pile une seule fois, il va partout avec moi, que ce soit en camping, rando-bivouac, au bureau, en balade, en soirée, bref toujours sur mon sac de rando ou sac à main. Il marche parfaitement. J'ai voulu en recommander deux pour un de secours et cadeau mais 47€ maintenant chez Amazon, je les ai commandé directement chez SunCompany. J'en ai eu pour 58€+20€ de frais de douane pour 2 unités soit 39€ pièce donc moins cher que les tarifs actuels amazon (16/01/25).
