I have been using this thing for about a week now. Thanks to Tropical Storm Cindy I have had plenty of dirty eggs to put in it. My observations so far:
Directions say to wash eggs for 10 minutes. I have found that best results come after about 20 minutes.
The egg washing powder that comes with it smells like laundry detergent and I suspect it is.
You will still have a little wiping to do when you rinse, but overall this does cut most of the manual labor out of getting clean eggs.
Would I reccomend it? If you're getting twenty plus eggs a day that are dirty...yes. if you are getting less eggs than that I probably would not bother with it.
The compressor for mine looks different from the advertisement.
