In general, I am satisfied with the tool. I did not underestimate the rating because of the case, these are my personal nitpicks. I would compare this grinder in terms of power with a 500w network model. You can’t cut the rails for her, but she cuts the profile pipe, fittings, bolts, nuts for a sweet soul. . The charge holds for 20-30 minutes, depending on the load. This is a good indicator for a stock battery. . Definitely recommend to buy, especially if you have another tool from this series, there will be an additional supply of batteries.
