Eggcellent peeler! I'm glad I followed their instructions because cooking eggs is a little different from what I'm used to do, but probably for a reason because it worked great! I needed dozen eggs for my pickled eggs recipe. I shook 4 at the time, since eggs were extra large. It took me literally seconds to peel them. Don't tighten too much to close!! First time I used it, I closed it to hard and it was a little challenging to open, maybe water had something to do with sealing it, but next two times I didn't tighten as much and it was perfect. Totally worth the money to save the time and hassle peeling them by hand.
