FYISWHO Silicone Watch Strap for Xiaomi Smart Band 10/8/9 (sport replacement band)

If you’ve worn your current band down, or you simply fancy switching up the look without replacing the whole fitness tracker, a silicone replacement strap can be a sensible move. The FYISWHO silicone watch strap is designed to swap onto specific Xiaomi Smart Band models and focuses on everyday practicality: a comfortable silicone feel, an aluminium buckle, and an easy-to-fit connector style.

Before you buy, though, it’s worth being a bit strict about compatibility—this strap is stated as working with Xiaomi Smart Band 10, 8 and 9, while certain “Pro” and “Active” variants are explicitly not supported.

What it is and why you might want it

This is a soft silicone sport replacement strap intended for Xiaomi Smart Band fitness trackers listed in the compatibility note. On paper, it’s a classic “replace the band, keep the device” approach: the tracker stays the same, but you get a strap that you can adjust more comfortably for daily wear.

The pitch here is mainly about comfort and routine usability. Silicone is lightweight and typically easier to live with for workouts and day-to-day wear, and this one is described as waterproof and durable—useful if you sweat, wash your hands often, or don’t want to baby your strap.

The essentials: comfort, buckle and build

The strap is made from high-quality silicone, and the description leans heavily on the practical benefits you’d expect for sport use: it’s comfortable, waterproof, lightweight and durable.

For security and day-long fit, it uses an aluminium buckle so you can attach, adjust and tighten the band without worrying about it slipping off. There’s also a straightforward adjustability via the buckle, which matters if you move between looser and tighter fits depending on the day.

Is it “premium” in the way metal watch bracelets can feel? Not really—this is silicone, so the appeal is comfort and ease rather than a dressy look. If you’re after that more refined feel, you may find silicone a bit too sporty.

How installation works (and where people get stuck)

The design uses interchangeable soft silicone strap ends with quick spring straps at both ends. It’s described as using Smooth Link technology: the pins are pushed into the watch shaft to lock both sides of the connector to the watch.

In real-world terms, installation usually comes down to lining up the connector, pushing the pins in firmly, then inserting the other end. It’s meant to be quick, but it can still take a couple of attempts to get the feel right—especially if you’re doing it for the first time.

Colour options and everyday use

The strap is described as available in various colours, which is handy if you want options for gym days, weekends, or just matching outfits.

A micro example: say you finish a run and want to keep wearing your band while you shower and go about your day. A waterproof, lightweight silicone strap is the sort of everyday helper that makes that less hassle than fancier materials. And if the band gets scuffed or you simply want a fresh look, swapping the strap is usually easier than living with a worn one.

What to watch for before buying

This is the part that really decides whether it’s worth your time. Compatibility is clearly limited to Xiaomi Smart Band 10 / Smart Band 8 / Smart Band 9.

Notably, it’s stated as NOT for Xiaomi Smart Band 8 Pro, NOT for Xiaomi Smart Band 8 Active, and also NOT for Xiaomi Smart Band 9 Pro and NOT for Xiaomi Smart Band 9 Active.

So it’s worth double-checking your exact model name before you commit. If you have one of the “Pro” or “Active” variants, this strap may not be a great match even if the numbers look close.

Final verdict

It’s a good fit if you want a comfortable silicone sport replacement strap for Xiaomi Smart Band 10, 8 or 9, and you like the idea of an aluminium buckle plus an easy swap design. The waterproof and durable angle also suits active daily use.

You may want to skip it if you own a Xiaomi Smart Band “Pro” or “Active” variant mentioned as unsupported, or if you’re aiming for a more premium, non-sporty look and feel.

If you want a straightforward band refresh without replacing the tracker, this type of replacement strap can make sense—just be strict about model compatibility first.
