I purchased this a year ago, but I'm no longer using it because I bought a different model. I had it glass coated immediately after purchase, so it's in good condition. Before listing it, I removed the limescale with citric acid and reapplied the coating. I think you'll be able to use it comfortably. The showerhead is easy to replace, and no construction is required. Even if you live in a rental, you can remove it when you move and take it to your next place. This ReFa head has received various positive reviews, and its performance is undeniable. I was able to experience its ability to remove dirt, such as oil from the scalp, and reduce the occurrence of acne. Your daily bath time will be enhanced, so I recommend it to those who are using the head that came with their new home or are looking to replace an old one.
