I'm on my third season with my original blades. I do not have any dirty ice where I fish.
Auger has been used ALOT
I'm gonna get new blades probably half way through season, my last trip I did feel I actually had to apply a tiny bit of downward force, whereas before, the auger literally pulled the drill through the ice.
I have not a single bad thing to say about the lite flite. I love it!
