FYISWHO 20mm Silicone Replacement Band for Amazfit GTS 4/4 Mini, GTS 3/2/2e & more (Quick-release, buckle clasp)
Product description
The essentials
If you’ve got an Amazfit smartwatch with a 20mm strap system, this FYISWHO replacement silicone band is designed to get you back to comfortable, everyday wearing without making it complicated. On paper, it ticks the boxes most people look for in a sport-style replacement: soft silicone feel, a lightweight build, and a metal buckle clasp for a straightforward look.
The bigger practical point is fit. The band is described as adjustable for wrists from 5 to 8.7 inches (130 mm to 220 mm), with multiple holes for sizing. That range should suit a lot of users, but (as always with strap replacements) it only really works well if your watch model uses the same band width and the pin system matches what you need.
There’s also the “easy life” angle: quick-release pins are mentioned, aimed at making installs and removals more trouble-free. If you’ve ever wrestled with a stiff strap change, you’ll appreciate that this one is built around swapping without fuss.
What you’ll notice day to day
This is a silicone sports strap, so the comfort story is mostly about material and wearability rather than anything high-tech. Silicone tends to feel more forgiving than rigid straps during movement, whether you’re heading out for a walk or doing a more active session like cycling. It’s also positioned as lightweight and soft, with a claim of durability for longer-term use.
The metal buckle closure is another small detail that matters in real life. It gives a clean, simple look and should be easier to handle than fussy clasps when you’re in a hurry.
For a quick micro-example: imagine you want a “clean” strap for office days and a sportier colour for evenings. Because the product mentions colour-matching with outfits and mood, it’s the sort of replacement people buy to rotate straps rather than “settle” on one option forever.

Where it shines (and where it can fall short)
This kind of strap is at its best when you want a simple, comfortable replacement band for everyday wear and outdoor activity—running, cycling, walking, travelling, and similar routines. It’s also a sensible pick if your current band is looking tired, you want a different colour, or you just prefer silicone for day-to-day comfort.
That said, it may not be the best fit if you’re particularly picky about the exact look/feel of higher-end straps, because this is positioned as a practical silicone replacement rather than something more premium in finishing. Also, while quick-release pins are mentioned, there’s no detailed compatibility guarantee in the info provided beyond the listed Amazfit models—so it’s worth double-checking your watch model and strap width before buying.
Compatibility & requirements
The band is listed as compatible with a range of Amazfit models that use this 20mm strap style, including Amazfit Active 3 / Active 2 / Active 2 Square / Active, Amazfit GTR Mini / GTR 42mm, Amazfit GTS 4 / GTS 4 Mini / GTS 3 / GTS / GTS 2 / GTS 2e / GTS 2 Mini, and various Amazfit Bip models (including Bip 3, Bip 3 Pro, Bip U, Bip U Pro, Bip Lite, Bip S, Bip S Lite).
There’s also a clear limitation: it is noted as not for Amazfit GTR 47mm. If your device is close in name but not in the list, don’t assume it will fit—strap width and pin system details matter.
Who it’s for (and who should skip it)
It makes sense if you want: - a comfortable silicone strap for daily wear and active time - a replacement band to refresh an older strap - the ability to swap straps more easily thanks to quick-release pins
You may want to skip it if: - your watch model isn’t clearly included in the compatibility list - you specifically need a different band width (this one is described as 20mm) - you’re expecting a strap designed for a very specific premium aesthetic (this is more “sport-friendly” than fashion-formal)
Final verdict
It’s a good fit if you’ve got a compatible Amazfit model that takes a 20mm strap and you want a soft, lightweight silicone replacement with a metal buckle and quick-release install. For most day-to-day situations—commuting, walking, training, and general wear—that’s exactly the kind of upgrade that actually gets used.
It might not be a great match if your watch model isn’t on the provided compatibility list, or if you’re trying to fit it to the excluded Amazfit GTR 47mm. In that case, it’s better to confirm compatibility first rather than risk an annoying mismatch.
