I got mine about 6 months ago, and I have yet to take it off. It's been amazing for uprooting plants, including yuccas, and I even popped a peach tree out of my neighbor's yard with little trouble. No visible wear, and it's preserving the lower edge of my loader.
If you need to smooth out an area, just roll the bucket so the heel is resting on the ground, and either use downforce or float depending on soil / moisture conditions. You can backdrag that and get pretty good results.
