Review: Its decent - color is great but it started coming apart and i feel like it would come clean off.
Review: Colours not great - Fits the older Whoop okay, plastic components which you would expect more or less but the colour is waaaaaaaaay off what's advertised. The Orange one is more like a safety cone orange, vibrant and fluorescent rather than the more muted tone you see here. Kinda garish and not what I was after. But it keeps the whoop physically on my wrist and so does the main job
