BYISYUE Silicone Replacement Band for Xiaomi Smart Band 8/9/10 (TPU strap)

The essentials

If you’ve got a Xiaomi Smart Band and you want to refresh the look (or replace a worn strap), a silicone replacement band is one of those small upgrades that can make day-to-day wear feel better. This BYISYUE option is designed specifically for Xiaomi Smart Band 10, Smart Band 9 and Smart Band 8, aiming to swap in easily and stay put during everyday movement.

It’s a straightforward silicone/TPU wristband approach: soft against the skin, lightweight for regular use, and built for the kind of sweat-and-dust reality that comes with workouts and outdoor days. Where it gets a bit less straightforward is compatibility — this one is clearly not for several “Active/Pro” variants, so it’s worth double-checking you’ve got the exact model before ordering.

Key features that matter in use

On paper, the appeal here is the combination of comfort and practical durability. The strap is made from TPU silicone, described as dustproof and waterproof, while still staying soft and lightweight rather than bulky.

The clasp design also gets a mention: a new strap clasp intended for more secure locking. In plain terms, that’s aimed at reducing the little annoyances where a loose strap starts to slide around or, worst case, feels like it could slip off during exercise. You also get simple installation, with one-button removal — useful if you like switching colours or you just want a quicker swap than wrestling with fiddly parts.

And yes, the strap comes in multiple discreet colours. That’s not a technical spec, but it does matter if you’re trying to match your band to your outfit for the office, the gym, or weekends outdoors.

What you’ll notice day to day (and what you shouldn’t expect)

This kind of silicone replacement band tends to shine when you wear your fitness tracker for long stretches — workouts, commuting, and general wear. The soft, lightweight feel is exactly what you want if you don’t want the band to feel like a chore.

You can also expect it to hold up better for active use than some more delicate-looking straps, especially given the stated dustproof and waterproof traits. That said, it’s still a replacement strap: it’s not trying to be a premium “upgrade to a whole new wearable”, so if you’re expecting advanced sensors or smart functions, this isn’t that. It’s purely a strap replacement.

Also keep in mind the compatibility limits. The listing specifically says it’s not for Xiaomi Smart Band 8 Pro / 8 Active and not for 9 Pro / 9 Active. If you own one of those variants, this may not fit as intended.

Where it shines

This is a good fit if you want an everyday, gym-friendly strap replacement for Xiaomi Smart Band 10, 9 or 8. The brand positions it for activities like running, cycling, climbing, hiking, camping, travelling, and general daily life — so it’s the kind of band you’ll likely keep on for training days and errands.

It also makes sense if you like having options: swapping to a different colour combination can be a simple way to keep your band looking tidy rather than worn.

A small example: imagine finishing a sweaty morning run and heading straight to work. A silicone TPU strap is often more forgiving to wipe down than fabric alternatives, and you’re not dealing with that “stays damp and uncomfortable” feeling for long — the comfort and waterproof/dustproof claims are aimed at exactly that rhythm.

Who it suits (and who should avoid it)

It suits you if: - You own Xiaomi Smart Band 10, Smart Band 9, or Smart Band 8 and just need a replacement strap. - You prefer soft, lightweight silicone feel for all-day wear. - You want something aimed at active use and outdoor movement.

You may want to skip it if: - Your device is one of the listed exceptions (Smart Band 8 Pro / 8 Active or Smart Band 9 Pro / 9 Active). Compatibility is the big “don’t gamble” point here. - You’re buying expecting extra features beyond comfort and strap security. - Your priority is a very specific fit/finish beyond what a standard replacement band offers (this is more “practical swap” than “bespoke upgrade”).

The essentials to check before you buy

Before you order, it’s worth taking 30 seconds to confirm your exact model. The listing is quite explicit about what it supports and what it doesn’t, so don’t rely on vague similarity.

You should also consider whether you’re buying for comfort, for durability during workouts, or mainly for style refresh. The strap’s silicone/TPU and clasp design are built around everyday wear and secure locking — if your main goal is fashion variety, the colour range is useful. If your main goal is sweat/outdoor wear, the waterproof/dustproof claim is the relevant angle.

Final verdict

Should you buy it? If you’ve got a Xiaomi Smart Band 10/9/8 and want a comfortable silicone TPU replacement strap that’s described as dustproof and waterproof, this BYISYUE band is a sensible, practical choice. The secure clasp concept and one-button removal also line up with what people usually care about when they’re replacing a band they use a lot.

Skip it if you own a Smart Band “Pro” or “Active” variant listed as not compatible. And if you’re after features beyond a strap replacement, you’ll likely feel short-changed.
