Made in a reliable factory! We've sold hundreds of these with no issues, but recently one was reported to have a screw come loose due to an oversight, so we've made improvements. This isn't a homemade product; it's a factory-produced item made from molds of genuine parts, so you can be assured of its quality! Ships within 24 hours. Compatible Models: Based on the parts list for 16.23 Larissa, 16.23 Despina, and 17.22 Hyper Force, it should fit if the pairing presser plate part number is 13LOE. 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 you can restore it to its original state after removal. I previously purchased and used sound-producing parts, but the sound was quieter than the Aorista, which was a bit disappointing. This time, I'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 homemade ones. I heard that someone with slightly impaired hearing couldn't hear the sound when they requested sound modification from a famous sound tuning shop, but they were happy that they could hear the sound from mine. 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 sound modification at your own risk. Will be shipped within 24 hours (excluding Golden Week and Obon holidays). ※Returns and claims are not accepted after purchase.
