I bought 2, one for each bathroom. Both shower heads from the start shot water in every direction from the water holes. I contacted customer service, they tried to say it was from buildup. When I asked if they sent me used ones they were confused, I explained that was the only way it could have limestone buildup because it happened straight out of the box. They emailed for a couple weeks asking questions but not offering a solution. Then they requested a video be sent in. Then they offered to send new shower heads. As of now I still haven't seen any replacement heads or a refund. The 3 stars are only because the water pressure is decent and the features are as advertised. Overall, not impressed with the product or customer service. Would not purchase again.
