I wasn't paying attention and did not notice that this one passed on a manual check. It initially failed due to wall thickness issues. It is now available. Note that the 5 slots are symmetrical. Meaning that the 2 far slots are repeats and of course the middle cuts the tube in half. So this really only offers 2 depths that are likely not as well calibrated as the 2.7/2.8 cutter. I would recommend the 2.7/2.8 over this but its up, I see its been passed for certain materials, why not.
I DO NOT THINK THIS ITEM WILL WORK, HOWEVER PEOPLE KEEP INQUIRING ABOUT IT.
