Made in a reliable factory! We've sold hundreds of these with no issues, but recently one case was reported where a screw came loose due to an oversight, so we've made improvements. This is not a handmade product, but a factory-produced item made from molds of genuine parts, so you can be assured of its quality! This is a set of a sound-producing unit and a special tool. Ships within 24 hours. Compatible Models: If the part number for the pairing press plate is 13LOE from the parts list of 16.23 Larissa, 16.23 Despina, and 17.22 Hyper Force, it should be installable. It should fit 16 Larissa~, 16 Despina~, and 17 Hyper Force~ and later models, but please purchase at your own risk. Please research the compatible models thoroughly before purchasing. ★Additional Note: Does not fit compact models. You can bend the sound-producing spring to adjust the tension to your liking. It can be installed without modification, and can be restored to its original state after removal. I previously purchased and used sound-producing parts, but I was a little dissatisfied because the sound was quieter than the Aolista. This time, we've improved the reel's loud sound (gentle on the brake core, so less wear) and had the sound-producing parts manufactured in brass at a factory, so I think it's more reliable than a handmade product. I heard that someone with slightly impaired hearing couldn't hear the sound at a famous sound-producing tuning shop, but they were happy that they could hear our sound. If you don't understand, you can search for "reel sound modification" on YouTube. Even beginners should be able to understand it quickly. Please perform the sound modification at your own risk. We will ship within 24 hours (Excluding Golden Week and Obon holidays) *Returns and claims are not accepted after purchase.
