In the end, all worked out well. However, when I was in touch with Support due to the UV not working properly, the first response was to suggest that I buy the part from Amazon and you folks would reimburse me for the cost. I refused for two reasons: 1) It is the responsibility of waterdrop to do the work and deliver to me the faulty part. Not me. 2). From past experience, fighting for reimbursement was not what I wanted to be engaged in. I wrote back with a succintly message, refusing to order from Amazon, pointing out again, the problem and outlining was needed to be delivered by you folks. Once done, the support got into action and swiftly sent the parts. My suggestion is do not ask the customer to do the order of a new part that should be provided by you folks. That put me off of Waterdrop. When my fellow condo owners ask, I will tell them of l my saga. YOu can improve by taking responsibility at the outset, and swiftly rectifying the issue at your expense.
