Yes. Just purchased this incubator two months ago. Thought I had checked everything out before using it and was sadly surprised. I only used one temperature gauge in my check. It was also off. My advise is to use two checks on temp and humidity. I purchased an inexpensive indoor temp/humidity digital gauge and a lab grade temp. only gauge. This can be done for about $25. You can check these two against your home heating system. Mine where both off 1 degree to the low side. This gave me a base. Using these two, I discovered that the temp was off 4-5 degrees on the low side. The humidity was almost dead on. I have now recalibrated the machine and in the process of rechecked it. Another problem with this machine is the hole for adding water only allows water into one side of the incubator. At lockdown, make sure you fill both channels before you put the eggs back in. I would purchase this machine again, but would do much more checking before I used it. In general., I like this machine. Hope this helps.
