Thank you for viewing. This item was purchased over 20 years ago. I used it about 5 times a year for the first 1-2 years, then about once a year after that, and it hasn't been used for the last 3 years. There are no particular problems, and there are no issues with normal use. For the last image, I will remove some parts for packing to sell at a lower price. Installation is not difficult, but I will provide support if you don't understand. There is not much difference from the current product, but there may have been minor changes. I will also include the manufacturer's information, so please check it yourself. Quoted from the manufacturer's website: Smooth and easy! Thoroughly eliminates line twist!! The pipe seat firmly secures large reels, and the automatic line twist removal rotation system rotates the spool when wound on the reel. The high-rigidity carbon body allows for smooth and easy winding even with strong tension, and can accommodate large spinning reels to both-axis reels. Supports single spools and 600m connected wide spools, eliminating the frustration of line twist and making your line last longer. Both-axis reels can also be used.
