Love the product; however the hand held I have replace at least 6x. The plastic knob that turns it off and for different sprays becomes useless. So I have ordered many more. Pay for the whole unit which is costly and only use the replaced handhold spray. As a result I have quite a collection of the product minus the handheld. At least 10. Waste of money when all I want to replace is the hand held. It would be helpful if I could just replace the hand held part. Not the whole unit.
