There are a lot of good products out there, but not everything is for everyone. What is not for one person might be the greatest product for ten others. What do you have sitting on the Back Shelf?
As do I... Another well liked product that is just not for me is the Vokshod blade. I used of bunch of them and just lost my tolerance of them over time. I have the better part of a hundred in the box of blades that will likely never be used.
