The product itself is great, not noisy, lighting is bright and adjustable. It has booster mode, the suction power is great when we put that on. It also has automatic mode and turns off on its own when done. However, when it arrived, it did not come with the pipe adaptor and screws, which we weren't made aware of. When the contractors arrived, then could only do what they could on the first day and delay installation until the new parts arrive 2 weeks later. Again that has nothing to do with the product itself, just be aware to check if everything is included as it should in the box before booking contractors to do the job.
