The item worked well but the internal battery lasted only 10.5 hours. For continual use, as was my intention, it has to remain plugged to a USB socket. For an item of this size and given the low power needed, I expected the battery to last much longer.

Prompt delivery, bought this to compare with my other reading devices, for temperature and pm2.5 kinda accurate as for the humidity can differ by 5 % Not sure about other reading as I breathing out my breath the CO2 fluctuates 3x so I think this is work fine
