I just got the R-com mini with scope. I*m only on day 2 of my first hatch, but this thing really does seem idiot proof. I went for the scope because I wanted to use it with my 4 year old and I thought it would be much safer than having him try to *help* me candle the eggs the old-fashioned way. If the set up is just for you or older kids then I would suggest saving the 50 bucks and just get the basic incubator.
