I have a 100% hatch ratio using mine as well. Of course those statistics aren't nearly impressive when I say I've only had one clutch of eggs.

All in all I love mine. For someone like me who has no talent building things, it was PERFECT. The size would be a bit small for someone who had MANY clutches of eggs to incubate, but for a hobbiest like me it's great. I also use larger tubs to incubate, so will limited on how many tubs I can fit in there.
