I have used this cutter on many jobs now and laid thousands of feet of flooring with it in tow. I use a stone to give it a quick sharpening before each job and still have no complaints. it still cuts straight and true like the first time I used it.
Makes me cutting an running vinyl siding so much faster, only negative is that it doesn't open a little wider to allow for thicker material. Blade is super sharp and will hopefully last a long time
