If I could give this product is zero, I would. Two units set up in the same room. Give two different temperatures and neither one is correct. These are clearly defective and not useful thermometers. Do not buy them for the price. They are very cheap. You know they came from Japan and probably only cost 10 bucks. Here’s the photo to prove it.

Just got them but if they give temp and humidity will be very pleased.

they are accurate and the right size for my needs

Accurate and perfect for the location.

So useful
