One of the cheap Chinese knockoffs was my first incubator also. I actually had decent hatches with it until the heating element and/or thermostat went out (on day 18!!) it wouldn't hold temp without a heat lamp over it. I suffered thru 3 days that way and still got a few to hatch.
But, the point I was going to make is even if the thermometer is fluctuating, the eggs take much longer to actually change internal temp. So slight fluctuations don't really hurt much, unless you have an extended high.
