I have used a lot of them in the last 2 years and think they do a good job. Have only burned up one 4 inch grinder using them in 2 years. I think it was $12 at HF for the first one. The replacement was $15 or $16.
The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself." - John Stuart Mill (1806 - 1873)
