Speed shuttle machine with 3-level adjustable launch angle. We attached it to a tripod used for cameras, etc., and used it for badminton receive practice. Although the speed and height may vary slightly with each launch, it's usable! Purchased new two years ago. I occasionally used it at home when the gym was unavailable. I've purchased additional shuttles, so there are about 50, which is convenient. - Model: Speed Shuttle Machine - Features: 3-level adjustable launch angle - Manufacturer: Field Force Thank you for viewing.
