I have an original ION and have no complaints. It's worked flawlessly for years now. I have the 8 inch auger now, but have been promising myself to get a 6 inch auger for my ION, but it keeps falling down the wish list. I spear or chase perch mostly, so I don't need a big auger that often and a 6 inch would make my battery last quite a bit longer. As far as blades go, you do have to watch where you drill as sandy/dirty ice will chew up blades real quick. If and when I need a new auger, it'll be a K-drill for this guy. I just like that setup.
