I'm pretty sure you will be happy with it. Mine has been running for almost 2 months straight without an issues and severla batches of eggs run thru it. The temp is always 37.5 on the nose...no matter the temp in my house and my house temp varies from 45F-98F (woodstove)...and it sits in front of a window. i have had thermometers all over in there and cant find any stops that are cooler even by 0.5F degrees.I almost bought the knockoff myself. They are all over eBay really cheap. I ended up buying the Janoel instead for $114. It was only $30 more than the knockoff so I went for it. I can't wait for it to arrive!
