I recently received them so I can't speak to their durability or how long they stay sharp (with proper care) but they feel like quality scissors. They have a nice weight to them fit my fingers comfortably and have a razor-sharp edge. I'm inclined to believe I'll have them for a long time.
They do a great job cutting they are bulky - I prefer the feel/grip of the Scotch sissors they are replacing. I'm sure the feel will get better as time goes on.
