I've only tried Feather blades a couple of times, and did not care for them. There are a few left and, as I do with every shaving product that I've tried and not liked, I will revisit them in the future.
Every time I've revisited(save one) I discovered a great product that did not work for me due to my own previous inexperience. I hope that this will be true for Feather blades as well.
