Review on CHAMPKEY Premium Polyurethane Golf Brush Star Series: Oversized Brush Head, Comfortable Grip, and Retractable Groove Cleaner for Superior Club Cleaning by Andy Mitts

Good concept but poor quality and design. The spike would be better if it could lock in the open position. That being said, you need to hold down the switch with your thumb while using it. More importantly, the retractable zip cord is not strong enough to support the weight of the brush. It unwinds a few inches just by sitting there, and when you pull it out it can't retract on its own. I just have to keep it in my pocket but that defeats the purpose. Dual composition brushes are good.
