Trusted the product reviews and bought it on June 14th. Used it almost every day (once a day, not intensively, but outdoors) for workouts. Today, June 24, requested refund (return window would close a week later in early July---am lucky to find out that the item is so bad).
Pros: heavy => additional weight for arms and better workout; indeed easily adjustable
Cons: after 8 uses, 10 days later, the middle part got so thin that the white thread inside is visible. Few workouts more and it will fall apart. This is unacceptable. I can understand few months, but a week of use... seriously?
Conclusion: Stay away from it if you are looking for something to last. I guess it will last longer if you only exercise on polished wooden floor. Concrete kills it in one week.
