FYISWHO Magnetic Watch Strap for Redmi Watch 4/5 and Xiaomi Smart Band 8 Pro/9 Pro (nylon sport band)
Product description
What it is and what it solves
This FYISWHO magnetic watch strap is a replacement band aimed at people who want to swap a standard sports strap for something softer and more breathable. On paper, it’s designed for training and everyday wear, with a nylon build intended to feel less “sticky” than some plastic-style bands, while still staying lightweight.
The magnetic clasp approach also matters for real life. If you’ve ever faffed with tiny clasps mid-workout, a quick magnetic closure is the kind of change you notice straight away. You can also adjust the fit using the strap length adjustment mentioned in the description.
Key takeaways
You’re basically choosing between keeping your current band or upgrading to a nylon sport replacement with a magnetic closure.
It’s a good fit if you prioritise comfort, breathability, and quick on/off when you’re heading out for a run, gym session, or a busy day at work. It may feel like a practical “daily alternative” to silicone-style straps, especially if you tend to get sweaty and want something that dries and cleans more easily.
Where it shines day to day
The strap is described as soft, flexible, light and breathable, plus washable and quick drying. That combination is especially relevant if you train often or live somewhere with humid conditions.
A small but practical detail: the strap is said to be easy to install and remove without additional tools, with a quick replacement time (around ten seconds) and a magnetic buckle for faster wear. In other words, you’re not just buying a new look—you’re buying less hassle.
Example use: say you wear one band for the gym and another for the evening. With an elastic replacement strap that’s easy to assemble, you can swap in seconds before heading out, rather than leaving your smartwatch stuck with one strap for everything.
Materials and comfort (the bit people actually care about)
The key selling point here is the nylon sport material. The description specifically contrasts it with plastic rubbing on the wrist, suggesting a more comfortable feel and less irritation.
That doesn’t mean it’s automatically perfect for everyone. If you’re used to a very rigid or ultra-supportive band, you might find this softer nylon style feels different on the wrist—more “sport fabric” than “hard strap”. Still, for everyday comfort and training, it’s built with that intention.
Compatibility you need to double-check before buying
Compatibility is where it gets a bit strict. The strap is described as compatible with these models: - Redmi Watch 4 - Redmi Watch 5 - Xiaomi Smart Band 8 Pro - Xiaomi Smart Band 9 Pro
And it explicitly states it is NOT for several variants, including: - Redmi Watch 5 Lite and Redmi Watch 5 Active - Xiaomi Smart Band 8, Xiaomi Smart Band 8 Active - Xiaomi Smart Band 9, Xiaomi Smart Band 9 Active
It makes sense if you already know your exact model name, but if you’re unsure (or you have a “Lite/Active” variant), you’ll want to confirm carefully first. With bands like this, the wrong model can mean it simply won’t fit as intended.
Colours and style: is it just for looks?
There are multiple bright colours, and the description frames this as a way to match outfits and personal mood. That’s not just cosmetic, because a sport nylon band can also make your daily wear feel less “techy” if you prefer more lively colourways.
Do note, though: if you’re after a discreet, neutral look, bright options might not suit you. It’s more of a “personal style” pick than a stealth, office-only band.
Care and washing
The strap is described as washable and quick drying, which is helpful for training-heavy schedules. Nylon straps typically handle sweat better than some materials, but you should still give it a proper clean when it gets noticeably dirty (especially after workouts).
Mini FAQ (quick answers)
Will this strap work with my Redmi Watch 5 Lite? No. The description specifically says it’s not for Redmi Watch 5 Lite.
Is the magnetic clasp convenient for workouts? It’s described as quick to wear during use, and the magnetic closure is part of the core appeal.
Do I need tools to fit it? The description says it can be installed and removed without additional tools.
Is it breathable and suitable for sweaty training? It’s described as breathable, lightweight, and quick drying, which points towards gym and training use.
Final verdict
Worth buying if you’ve got one of the listed compatible watches/bands and you want a breathable nylon sport replacement with an adjustable fit and a magnetic closure for quicker on/off.
Better avoided if you own a “Lite” or “Active” variant (or the non-Pro versions called out in the exclusions), because compatibility is explicitly limited. Also, if you prefer very rigid straps or ultra-minimal looks, the softer nylon feel and bright colour options may not be your cup of tea.
