Review on WINGONEER Temperature Humidity Thermometer Hygrometer Heating, Cooling & Air Quality by Mark Erandio

These thermometers + relative humidity meters are really terrible. Pros: - They arrived intact - They already had a battery installed (and both units were already on which drained the batteries but I saved a step) - I haven't contracted Covid from them yet. Cons: - To change from grade C to grade F you need to put a screwdriver (or other conductive metal) through the hole in the PCB and short 2 pins. It's pretty smart, but also very cheap. 1 of the 2 meters I got does not convert from grade C to grade F simply because there is no cheap jumper on the board (I know from disassembling it). Cool - The screen is unreadable unless you're reading it up close. If you tilt the screen more than 15-20 degrees, you only see 88.8 °C and 88%. - I sat with the two side by side for an hour and they showed different temperatures. I understand they have such a large margin of error but still quite disappointing. I certainly wouldn't buy them again unless I was giving them to a child to play with, or I had a very specific use case that the above cons don't help. It doesn't matter (like I got married and had something new, something borrowed, but I didn't have anything blue).
