This is a good solution for those who don't want to scratch their wheels by removing nuts with an impact wrench. The sleeve perfectly protects the paint when using an impact gun. Unfortunately, the plastic cover is rubbish. Mine broke after 8 months of inactivity and use (4-8 bikes per month). Powerbuilt outlets are made in Taiwan for those of you who stick to these facts. I would give this 5 stars if the case was more durable. I'll try to get it under warranty but I'm not holding my breath.
