Purchased from Amazon Outlet last year. Used a few times indoors when I first started playing golf. There is a tear in one part of the box from the time of purchase, which has been repaired, but the main body is almost new, and there are no problems with use. There is no warranty, but how to use it can be found by searching the internet. [Product Description] This is a 75cm long swing training device that allows you to learn the swing rhythm with a "flexible" shaft and a sound function that makes a sound at the point of maximum acceleration. The shaft is moderately soft, so you can experience the speed and timing of the swing's transition, and the points of the swing's movements from the downswing to the impact through the "flex". When the point of maximum acceleration is reached, a "click" sound is produced, making it easier to swing with awareness of the impact zone. Your swing rhythm will naturally improve, and your head speed will also increase. The head part has a lie angle modeled after a 7-iron, so you can practice arm rotation. Material: Grip/Synthetic rubber, Shaft/POM, Head/Elastomer resin, Steel ⚠️Will be sent in simple packaging. Please check the condition carefully as it is not new.
