I bought two of the reptile therm/hygro cage accessory. One is in the LG and one in the Genesis 1588. In the Genesis, I don't use any other except my meat probe digital to check corners( I have no problem poking extra holes in my bators). . I use lots of little thermometers in the Still air LG because I like to compare which corner is cooler than the others. But I always trust my reptile duo one first. My daughter raises Bearded Dragons. She told me that the one she uses keeps her lizards alive, breeding, and thriving. I trusted her advice and bought what she uses. You get what you pay for as the saying goes. I tossed my cheap ones. They were worse than useless because they were too off to be trusted.I usually have very good luck with my LG still air. Take a plastic milk cap and a screw and put it in the top of the know for adjusting the temp. Save the box and leave the incubator inside (Cut the top off. It really makes a difference with temp fluxuation. Put a small cup (I use a paper bathroom cup and put a sponge in) in the incubator instead of pouring water into the channels in the bator itself. You have a better chance of adjusting the %. Be sure to put the cup under a hole some where so you can put a straw in to pour more water in without opening the cover. I'm not a stickler about not opening the cover as hens are on and off continually. 2 hatches ago 4 separate eggs had pipped when I was candeling, I put them back in and all 4 hatched. The previous hatch, I did everything by the book, Only 1 hatched out of 12. I like mine but then my chickens are not big bucks chickens either.
I can't get the 3rd pic to download that shows the milk cap. I'll try later. There are other tips here on BYC.
I hadn't seen Mumsy's piece on that thing but yes! I'd like to know tho, where does everyone go to get an accurate thermometer? I have up to 10 of them and honestly, I only have 2 that are somewhat near each other. I hate going anywhere reptiles or their accessories but I'll check there. I have 2 brand new digital from Walmart and both are off
