Using the Lezyne Matrix Saddle Tagger is easy. First, find the seat rails of your bike. Then, attach the holder to the rails using the included TR25 security bolt with the IP67 waterproof - rated twist - lock design. Make sure it's firmly clamped. Insert your Apple AirTag (not included) into the holder. You can then use Apple's 'FindMy' network on your device to track your bike if it gets lost or stolen. When it comes to maintenance, since it's IP67 waterproof - rated, it can withstand some water exposure. But try to dry it off if it gets wet. Check the clamp and the security bolt regularly to ensure they are tight. Don't use sharp objects on the holder to avoid damage. Also, keep in mind that this product works with Apple AirTag only and AirTag is a trademark of Apple Inc.
