Review: Perfect Fit and Great Quality Replacement Strap - This MOOFIT RA1 replacement armband is exactly what my wife needed for my heart rate monitor. The 24.5 mm width fits the monitor perfectly, and the strap feels durable without being stiff. The adjustability is excellent, plenty of length to get a secure, comfortable fit whether you wear it high on the arm or lower near the elbow. Compatibility is spot‑on, it connects perfectly with my wife’s device, and the material feels comparable to the OEM straps and it functions equally as well. The strap does not affect battery life or accuracy of the monitor, and does not cause any kind of sensor reading lag. For a simple replacement band, it delivers great build quality, comfort, and reliability. A true five‑star upgrade. For under ten dollars!
Review: Nice option for Visible 2 monitor - I got this band to replace the thinner elastic band that came with my Visible 2 armband monitor. The fit is good, the medium size is very close to the same length as the original band. It fits through the "arms" on the Visible well, but doesn't dig in as badly as the other elastic. It's softer, more clothlike. It does have a tag sticking out, but it is easily snipped off. The grey color is more subtle that the black. A nice replacement band for the Visible 2.

### ⭐⭐⭐⭐ Good replacement band but funky to get on
*by J***K on November 14, 2025*

The strap fit my device perfectly. I wish the Velcro tab had a little more length. If you fit it properly to your forearm you have to either stretch the band or loosen the Velcro, and it is so short that it very easy for it to slide back through the bracket and fall out. A longer distance to the Calero tab would let you loosen enough to slide it on and then secure it.
