Bcuckood Elastic Nylon Straps for Samsung Galaxy Fit 3 (SM-R390) – 2 Pack Adjustable Stretch Wristbands

If your Samsung Galaxy Fit 3 strap feels a bit tired, stiff, or just doesn’t match your outfits, an elastic nylon replacement is a sensible route. The Bcuckood Elastic Nylon Straps are designed specifically for the Galaxy Fit 3 model number SM-R390, with no tracker included. On paper, they focus on comfort, breathability and easy swapping — the kind of upgrade you notice day to day rather than in a spec-sheet showdown.

The essentials

These are replacement wristbands made from soft, stretchy nylon. The idea is simple: a lightweight strap that’s breathable for everyday wear, plus enough elasticity to be comfortable for a wider range of wrist sizes. They’re also washable, which is a practical point if you wear your fitness tracker often or you’re the sort of person who ends up with straps that need a refresh.

The strap uses a classic ring clasp for adjustment, and the pack includes two straps. Colours are designed to “pop”, so if you like having options for different outfits (or just prefer something less plain than a standard band), this set leans into that.

What you’ll notice in everyday use

Elastic straps tend to win on comfort: there’s less of that rigid, “new strap” feel, and the stretch makes it easier to take it on and off. Here, Bcuckood also emphasises breathability and a lightweight build, which matters if you wear your Galaxy Fit 3 for long parts of the day.

There’s also a slightly fiddly but important installation note: after you slide the band into your Fit 3 with the stainless steel connector, you need to push it in with more force to help ensure it doesn’t fall off. It’s one of those instructions that’s easy to skim, but it’s worth taking seriously if you want a secure fit during normal movement.

A quick micro-example: imagine heading to the gym, swapping from a darker band to a brighter one before you leave. With no tools required, you can do it in seconds — but you still want to follow the “push in with more force” step so the connector sits properly.

Fit, adjustability and sizing limits

The adjustable stretch design is claimed to suit wrists from 145mm to 250mm (5.7" to 9.8"). It’s also positioned as wearable for both women and men, which mainly comes down to the elasticity and the ring clasp adjustment.

One limitation to keep in mind: this band is only compatible with Samsung Galaxy Fit 3 SM-R390. It’s explicitly stated as not compatible with other watches, so if you’re shopping for a generic “replacement strap”, this isn’t that.

Where it shines (and where it may not)

This set makes the most sense if you prioritise comfort and day-to-day wear. Breathable, washable nylon and an elastic fit are a good match for people who wear their tracker frequently and want straps that feel comfortable rather than bulky.

It’s also a decent choice if you like variety: two bands lets you rotate them, and the colour options are meant to go with a wide range of clothing, including casual looks like string or beaded bracelets.

However, it may not be the best choice if you’re looking for a very “structured” strap feel. Elastic nylon is more about comfort and flexibility than a stiff, fashion-watch-like profile. And because this is replacement-only (no tracker included), you’ll need to already own the Galaxy Fit 3 (SM-R390) to use it.

Quick install and the compatibility reality check

Installation is described as tool-free: you slide the band into your Fit 3 tracker using the stainless steel connection adapters on both ends. That’s convenient, but the compatibility note is crucial.

Before buying, double-check that your device is Samsung Galaxy Fit 3 with SM-R390. If the model number doesn’t match, don’t assume it will fit — the listing is clear that it’s designed for that one compatibility window only.

Final verdict

Worth buying if you want comfortable, breathable, washable replacement straps for a Galaxy Fit 3 SM-R390 and you like having colour options (two straps for rotating is handy). It suits everyday wearers who want an easy swap without tools.

Skip it if you’re not sure about the Fit 3 model number, because these straps are stated as not compatible with other watches. Also consider whether elastic nylon is the feel you want, if you prefer a firmer strap, it may feel a bit too flexible for your taste.
