Yes South, lots of problems. They were really good about it and I love my laguna saw, but won't even run the four new blades I have hanging on the wall as I found every one of them to have been a waste of time.
the trimaster lasts a long time and does a good job, but if you are going to cut glass with it, I wouldn't waste my time trying to have it sharpened weather they will or not. It will just get dull immediately after the first time it cuts glass.
Strangely, it cuts nearly as well on glass while being dull as a regular blade will cut on wood mostly sharp.
