Well those are certainly better than those useless stick-on plastic ones BUT whilst the thermometers on them are fairly reliable I found the hygrometers to be less so ..

I got the exact same ones off eBay for 2 dollars each including postage soooooo the quality isn’t going to be great .

Rightly or wrongly I don’t pay too much attention to humidity and just spray the vivs daily .. and increase the spraying when in shed mode
