FYISWHO silicone replacement band for Redmi Watch 4/5 and Xiaomi Smart Band 8 Pro/9 Pro
Product description
The essentials
If your fitness tracker band looks a bit tired, a replacement strap can be the easiest way to make it feel “new” again. This FYISWHO replacement silicone band is designed for specific Redmi Watch and Xiaomi Smart Band Pro models, aiming to be comfortable for everyday wear while still staying practical for active use.
On paper, it ticks several boxes: it’s made from soft silicone, it’s lightweight, and it uses a metal buckle closure for a straightforward, neat fastening. There are multiple adjustment holes, so you’re not stuck with just one wrist fit.
That said, compatibility is the big thing to get right. The listing is clear about what it supports and what it doesn’t, so it’s worth checking your exact watch/band model before you order.
What it’s for (and where it fits in)
This strap is aimed at people who want a simple sport-style look and a comfortable feel for regular wear—think desk-to-gym routines, commuting, and all the usual “wear it most days” scenarios. The silicone material should sit nicely on the wrist without feeling stiff, and the buckle closure is intended to be reliable for daily fastening.
If you’ve had a previous band stretch, discolour, or simply lost the look you wanted, swapping in a replacement can be a sensible, lower-cost alternative to replacing the whole wearable.
Key features and what you’ll notice day to day
The main user-facing benefit here is comfort. Silicone tends to be a forgiving material against skin, and the strap is described as lightweight and soft. In practical terms, that’s the kind of upgrade you notice more over time than in one dramatic moment.
For fit, the band length is listed as suitable for wrist sizes from 5"–8.7" (130mm–220mm), with multiple alternative holes. That gives you some room to fine-tune the tightness so it doesn’t end up either too loose (slipping) or too tight (uncomfortable).
Installation is also designed to be painless. The listing mentions upgraded quick release pins, with the expectation that you can install and remove it easily, without the strap “crashing” or coming loose.
There are also various colour options, which makes it easier to match your strap to outfits or to switch it up when you’re bored of the same look.

What matters before you buy
Compatibility is the one area where it’s easy to get caught out. The listing explicitly says it’s not for several similarly named variants (for example, “Lite” or “Active” versions for Redmi and non-Pro versions for Xiaomi). If your wearable model name isn’t an exact match, you may want to skip this band.
Also, bear in mind that while the strap is described as durable and comfortable, the comfort you feel will still depend on your skin sensitivity and how tightly you like to wear a band. Some people prefer a softer “barely there” fit, others want a firmer feel.
If you’re prioritising an easy daily swap and a sporty silicone feel, it should make sense. If you’re after something more premium-looking or more “dressy”, silicone won’t be the direction you want.
Is it worth it?
Buy it if you have a compatible Redmi Watch 4/5 or Xiaomi Smart Band Pro model, and you want a practical replacement strap that’s soft, lightweight, and adjustable with a metal buckle. It’s also a reasonable choice if your current band is worn out and you’d rather refresh the look without replacing the wearable.
Skip it if your model is one of the listed “not compatible” variants. In that case, the band may not fit correctly, and you’d be better off choosing a strap made specifically for your exact device.
