FYISWHO Magnetic Nylon Watch Strap for Redmi Watch 4/5 and Xiaomi Smart Band 8 Pro/9 Pro
Product description
If you like your smartwatch bands to feel light, breathable and easy to swap, this FYISWHO magnetic nylon strap is designed for exactly that kind of day-to-day use. It’s a replacement option built around a soft, washable nylon feel and a magnetic closure that’s quick to fasten.
That said, it’s not a universal strap: the compatibility is specific, and the manufacturer explicitly excludes several “Lite/Active” variants and some Smart Band models. So it’s one of those purchases where checking the exact device model matters as much as liking the colour.
The essentials
This strap replaces your current band for compatible Redmi Watch and Xiaomi Smart Band devices. Over the course of a typical week, the biggest practical difference is how it sits on the wrist: the nylon material is meant to be soft and flexible, breathable enough for everyday wear, and quick to dry if you’ve been out training.
The magnetic clasp is also a comfort-focused choice. Instead of wrestling with tiny holes and pins, you can clip it on and off more readily. It’s the sort of design that works well if you take your watch on and off often, or if you want something that’s simple during a busy morning.
What you’ll notice day to day
On paper, this strap is aimed at people who find silicone-style bands either too sticky or too “plastic-y” in hot weather. The nylon construction is positioned as more comfortable against the skin and less likely to rub than harder materials. There’s also an emphasis on sweat management: the fabric is described as allowing sweat to escape and drying quickly.
A good real-world micro-scenario: you go for a run, the strap gets sweaty, and you don’t want to leave it to dry for days. With a breathable nylon band that’s described as quick drying and washable, it fits the rhythm of training and everyday wear.
Key features that matter (and where it may fall short)
The setup is described as easy. The strap is intended to be assembled and removed without additional tools, with a quick change time of around ten seconds. The band is also adjustable, thanks to the way the length can be set on the nylon strap.
The magnetic closure will feel like a win if you prefer quick fastening. However, it’s worth noting that magnetic clasps aren’t for everyone—if you’re very particular about how secure a band feels, you’ll want to pay close attention to fit and adjustment.
Also, while it’s designed for training and regular wear, it’s still a replacement strap. If you’re looking for something more premium in finish or a more rigid “dress” feel, a sport-style nylon band may not be the right vibe.

Who it suits best
It makes sense if you want a practical, washable alternative to silicone bands and you’re after a comfortable strap that works for training and everyday wear. The multiple bright colours are also clearly part of the appeal—if you like matching your band to your outfit, you’ll probably enjoy the variety.
It’s also a sensible pick as a replacement band, rather than buying a whole new wearable.
It’s not the best match if you need compatibility with the excluded Lite/Active variants or other Smart Band models mentioned above. In that case, you’d likely waste time trying to make it fit when the manufacturer’s guidance says it won’t.
What to check before you buy
The biggest thing: confirm your exact watch/band model first. The compatibility list is fairly specific, and the exclusions are explicit. If your device falls under one of the “NOT for” categories, skip this strap.
Next, think about closure preference. If you tend to prefer pin-and-hole adjustment or you’re cautious about magnets, double-check how the clasp sits once fitted.
Finally, consider your use. If you mainly want a strap for low-sweat desk days and you prefer a more formal look, this sport nylon design may feel a bit casual.
Should you buy it?
Worth considering if you have a compatible Redmi Watch 4/5 or Xiaomi Smart Band 8 Pro/9 Pro and you want a soft, breathable, washable nylon replacement strap with a magnetic closure for quick fastening. It’s especially appealing for training days and for anyone who finds silicone bands uncomfortable over time.
You may want to skip it if your device is one of the explicitly excluded models (including certain Lite/Active variants), or if you strongly prefer a non-magnetic closure feel.
If you’re happy with a sport-style band and you’ll actually swap it around, this FYISWHO option looks like a straightforward, everyday upgrade rather than a premium makeover.
