The fusion is an excellent cart thats for sure. However its so expensive and takes the fun out of shaving. Not to mention that I can notice the carts degrade after 2-3 shaves, and it gets to a point were it just becomes really annoying to shave with. I'd rather shave with 1-2 times super sharp blade, and toss it for a fresh one.
This.
You can get an awesome shave from a fusion for sure. Costs you plenty though.
