Looks like the blue is gone, the red is still ok https://www.amazon.com.au/dp/B07TD8NK84?th=1.
Was looking for a reasonably priced band and found this. Available in blue and red at this price. This seems to be a price error or this is just the band but that's not what the description states… No idea about the product quality. At this price, I would not expect much… Amazon reviews seem OK even though some complain about accuracy and battery life.
