I used to own a Piao I Teapot, but it broke. The stainless steel ball came loose, and I had no idea how to fix it. I couldn’t find pictures of what it was supposed to look like, and no one could tell me how to put it back together. Since I bought it when on vacation in Seattle but live in Maryland, I couldn’t just go back to the teashop where I purchased it. It took me forever to figure out how to fix it, and even then, it wasn’t a lasting solution.
In the end, it turns out that this product was not made to last. Apparently if the mesh strainer doesn’t stay down, the whole thing comes apart and the ball moves off the track. I tried super gluing the mesh strainer back in place so that it would stay down, but even that didn’t work. It kept popping up anyway any time I turned it upside down, which I had to do to clean it. Tea leaves really stick to that thing!
So while it was great while it lasted, I can’t recommend this infuser. Your money is better spent elsewhere.
