Sun Company MiniThermometer - Zipper Pull Mini Dial Thermometer with Split Ring | Easy-to-Read Outdoor Keychain Temperature Gauge for Jacket, Parka, or Backpack

Pretty easy to read and seems accurate. For what it is... seems rugged enough.

This tiny thermometer appears to be very well built. It's accuracy is fairly good. In as much as it is very small and difficult to read it doesn't matter much if it's off by a few degrees as it is at best read in three or four degree increments anyway.

This is the most accurate thermometer🌡for it's size compared to other thermometers I have bought. It is consistently accurate in cold and warm weather.

We use this thermometer to watch for elevated temps inside the fuselage of our B-25 while on the ground during airshows. It's hanging inside above one of the waist gunner windows. If the interior gets over 100 degrees, we don't allow tours. It works great, but I wish the dial was a bit larger.

Doesn't tell right (80 out show 100)temperature, very very small.

Its' a great back-up to my larger thermometer. Small but accurate

This is great small enough not too be noticed and accurate enough to be within a couple degrees! I personally replaced the key ring with my own spliced lanyard cuz i don’t like key rings

Needle was so large compared to the numbers that you couldn’t tell the temperature very precisely, maybe +\- 5°. Then after a couple of months the thermometer fell out of the plexiglass base.
