Used for about 2 years. Overall, there are scratches and dullness. The water-saving switch is somewhat loose. The adapter used was KVK. I am selling this because I have replaced it with a new series. I hope to connect with someone who is interested. This is a used item. I don't think it will have the same effect or water pressure as a new one.
