Incubator Temperature Controller

I was thinking that I should put this link on here for this temperature controller,
 I have a couple of these and have had no problems with them.

I was thinking that some of you could use it in an egg incubator , I also have a twin one with the humidity control. they a good as they have a heating and cooling control.

I use one of these with my slow cooker. for Sous-vide cooking. and I have one running my propagator at the moment with the sensor in the soil.
