I have had mine for over two years. I also have the wide blade attachment thing and use this 90% of the time. I never did like the chisel port, because there is too much play in it. It is easier for me to use the top instead of the port. Also, with the port, the same space on the sandpaper gets over used.
It is my "go to" sharpener. I can get dull previously sharpened chisels and plane blades with no nicks in them, to 6000 grit in no time at all. The leather hone is great for getting rid of the burr and putting a fresh edge on a slightly dull edge.
I have bought a few glass discs and keep them separated by grit. I also buy my sandpaper from auto stores, because they have higher grits in wet/dry in my area, but you can get sandpaper anywhere you find it. I use spray adhesive on the glass discs and put the sandpaper right on it. After that, I just cut around the edges and poke a hole in the middle. Pretty simple. When it is time to switch it out, I pull off the paper and use some mineral spirits and put a new sheet on.
For tools that have nicks and are messed up, I use 80 grit and get a fresh edge on it, then go up through the grits.
Also, before I forget, I keep a small container of water next to it and dip the chisel/plane into it and wipe it off, after every grit or when I feel heat.
For me it is the same thing as using sandpaper on glass or even using stones, except the the worksharp is moving, instead of your arms/hands. I also hated sharpening that way, because my hands always started to hurt after a few minutes because of the repetitive movements.
