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

Buy original Whoop instead
Overall ok if you are in need of a band and short on cash, however I am returning this as 1) it isn't the colour in the picture (I wanted pink/magenta and received brick/dark red); and 2) it smells really bad like a mix of cheap plastic and vinegar. I'll fork out the extra dough for the original at the Whoop store.
