Decent meter, wish it had a temperature function, the ambient temperature shown isn't very useful, I don't worry about the room temperature most of the time. I think the IC that the meter uses has a built-in temperature sensing function, so turn it on. The large display on the left is good, the small display on the right is blocked at the top and you have to look at a low angle to read the temperature. The fit seems to be good. I like that it uses 18650. This speaker is bad, any bass in your music will sound terrible. Using your phone's equalizer to get rid of the bass might be fine for background noise. I'm picky about the sound quality so it doesn't suit me.
