【We inspect the unit multiple times before listing and shipping】 ★ This is a common unit for the Disk System and Twin Famicom. ★ If you have a unit with a belt replacement & maintenance already done, it's easy to swap it into your main unit. You can enjoy Disk System games and Twin Famicom games that you were unable to play. ★ We will include a memo with instructions on how to swap the unit at the time of shipping, so please refer to it. ★ The belt uses a new, genuine rubber belt. We are confident in its durability. ★ While Mobilon bands can be used as a temporary substitute, they tend to stretch and slip after a few months. ★ Tested with approximately 10 disks. We will re-inspect before shipping. ★ Maintenance includes cleaning, head adjustment, and applying grease to necessary areas. ★ The item for sale is only the unit in image 1 (late model). The entire main unit is not included. ★ We plan to ship via Letter Pack Plus (shipping method may change depending on circumstances). 【60-Day Peace of Mind Guarantee】 Repair costs and shipping are free for the first 30 days from the date of purchase. For the following 30 days, repair costs are free, but shipping costs are the responsibility of the buyer. ※ We recommend using this with the original Nintendo Famicom.
