Hi @ronott1 I use the Brinsea last year and the results were good but not as great as I had expected. This year I purchased one from Maficfly and it works a lot better than Brinsea in terms of light intensity. At 17.99 its not too bad. There are only 2 cons I see:
a) Does not work with batteries. So if you have a power outage problem then not good for you
b) If you want to keep your hands free while examining the egg, thats not possible like in Brinsea.
