After trying this industrial power tool, I must say it exceeded MY expectations... It is very efficient and made my task easy. the product is durable as I have used it many times. This tool is a great investment for anyone working in the industrial and scientific field. The only downside is that it is a bit heavy to handle, but that is expected of any surface grinding tool. Overall, it's a must-have for anyone in need of a powerful and reliable industrial power tool..
