"Functionally, this thing works great. It's extremely quiet at the lowest level, perfect for microscope work, and the remote makes it easy to increase suction for heavier soldering jobs. The long, rigid hose stays in position, and the multi-layer filter does a great job trapping fumes and odors. Built like a tank with solid metal construction and great attention to detail. It's expensive, but given its build quality and performance, it's worth every penny. Excellent buy!"
