I’ve had excellent service over the years from B&D power tools. Admittedly, I’ve never bought a compressor from either, but I wouldn’t hesitate for a moment if the price was right. I have a B&D reversible drill that I got as a gift 40+ years ago and it’s still in use. I have a B&D multifunction lithium-ion tool that I bought some years ago that I use regularly. It has a circle saw head, a drill head, a surface-cut oscillating head, and a few others. Kobalt is relatively new to the world of home power tools, but I’ve looked at them at Lowes and they look solid. I’d buy one if the price were right.
I’ve had excellent service from and been happy with Ryobi tools too. They’re a bit lower priced, and perhaps not for pro use, but I’ve been happy with mine.
