Still need help? Here's the step by step breakdown.
Start by identifying the notch side of the case.
Hold the sensor at a 45° angle and slide it into the notch, then apply just enough pressure for it to stay in place. Do not push too hard.
A small gap at the top is completely normal. Note that you should not hear a "click", this is a push-fit connection, not a snap. And keep in mind that the harder you push it in, the more force will be required to remove it later. Do not push too hard.
Take the buckle and insert the long arm first through the nylon strap loop. Make sure the orientation is correct, the flat side of the buckle must face outward. Never insert it with the flat side facing inward, this is the most common mistake and will affect the fit.
Place the strap with the velcro side facing up (visible side). Thread the strap back through the buckle.
Important: the gap between the buckle and the metal case should be as small as possible. Slide the strap all the way until the gap is minimal. If the gap is too large, the strap won't sit at the right size on your wrist.
Yes, our products are specifically designed for the Amazfit Helio Strap and Helio Core.
No, the official Amazfit band is not compatible. Our case is designed to work with 23mm wristbands with a velcro closure.
You can purchase a compatible 23mm wristband from the Polar Loop store - their bands are fully compatible with our case.
The case and band can handle water exposure such as rain or handwashing. However, we do not recommend prolonged use in chlorinated water (swimming pools), as chlorine can damage the anodized finish over time.
No. The case is made from CNC-machined aluminum with an anodized finish. Anodizing creates a protective oxide layer on the surface that prevents corrosion and rust. This is the same finishing process used on MacBooks and Apple Watches.
Built to handle daily wear for years.

Make sure the aluminum buckle is positioned close to the case, not on the opposite side of the wrist. This makes a significant difference in how the band fits.
