I have great hatches in my LG incubator , you just have to find your mojo as with any incubator thats why they say run them first for a few hours or even a few days before adding eggs this way you know what kind of temps you will be dealing with
TSC also gives you a full refund if your not happy with them as long as you don't soil it.
Give it a try the most and worst thing that happen to me was my eggs were not fertile in the first place.
Get a fish tank thermometer from
walmart or any where for that matter they are under 2.00 it will be your best friend through your whole hatch.
The digitals always go crazy up and down cause they are so sensitive.
The nob to the heating element is also very sensitive one to many turns or one turn in the wrong direction will mess up
cheap incubators shouldn't be left alone in a room that changes a lot in temperature from highs to lows, it took me and my daughter watching 2 LG Incubators taking turns to figure out what was the best route to take.
Make notes of any changes you do and make sure you write down the time next to it.
This takes a lot of the guess work out of hatching.
