I bought the smaller Ekich and after a month or so decided to try my old Rite bobbins again. It made me realize how much I relied on the features of the automatic bobbin and I have not touched my older bobbins after that, and I also ordered the larger one for steelhead. I still use a conventional bobbin when I am using the smaller spools of silk, but the Ekich has been worth every penny to me. Great bobbin. I like the fit in my hand better than the Nor.
