I am concerned though that it could break more permanently while adjusting the height. Yes, now the "stem" is made out of paper. The soundproof, I hear nothing but the music played over the Bluetooth! The sandals are very comfortable and Im extremely satisfied with my purchase. Excellent visibility too. Comfortable and smart. Since they were meant to be a surprise, there was no information regarding the sender on the box so she was not aware who sent them to her. When Im working out it seems to work better though, and maybe thats because its tracking the entire time and not every 5 minutes. A good budget wheel if its the only one in your price range. I own two, and have purchased 3 for other employees.
