Got one as well, and love it. When I recently re-calibrated my TS, wow what a difference. I have a contractors saw and was able to set the blade at perfect 90. I also set the stop at 45 perfect. I love it. Used it on my CMS, which I thought was set pretty close. To my amazement I was at 92.8 when I set it by hand using squares. It to is at 90 now. My FIL now wants one. I see a B-Day or Fathers Day gift in his future.
On the TS, love the fact that I can calibrate the gauge, attach to the blade, and set the angle that I want. No more guessing on the somewhat accurate needle gauge that came with the saw. The small price of the tool has outstanding qualities.
