Product review (4 stars): Handy, good color, easy, good magnets, just average display for brightness
Just got these. Put the battery in and switched to F. Good to go. Great little magnets. Stuck them up in two different rooms. We're in a horrid heatwave. First temp to register was 96 inside. Pretty color. Small size but no tiny. Make sure you read the dimensions, I think about 1 1/2 " tall by 2 1/2" wide and under an inch deep. I plan to put one in my car. Might buy another set. Only complaint is the display is not bright. Typical dark digital display, not well-lit like in the illustrations. Batteries were included. Arrived safely boxed for combat. With Prime I had them about 15 hours after I ordered. Happy.
