I like them a lot, I have them on 8 saws i think
anyhow, I have one on my G660 saw that I use on my logosol CM that I have had for 2 yrs. now and no issues, I know some people claim it will melt the cover
but it won't. If it would have melted the case and cover it would have been this Stihl knock off, and I would have noticed it. I do run my CM at 32:1, so Ya the case is a bit black, who cares, it's a work saw not a shelf queen LOL. Jason's customer service is top notch, I use Him and Tree Monkey to do my port work. I have not tried the deflector yet. people have them on their saw and love them. the quality is better than the WCS BB, and better priced too. and there is a guy that compared the two, and the Egan S.S. kept saw cooler, and cut a bit faster.
