the design is amazing. just as described

Okay, honest review, no BS. First, 5 stars, but the sensor accuracy's a bit off. For the price, I expected "you get what you pay for," but this RO9+ is awesome. Just needs software polishing for the step sensor; it'll be almost as good as my Samsung watch. 4 stars because the sleep sensor is way off compared to my Samsung watch. A little software fix should solve that. The battery's amazing—easily 5 days if you set everything to measure every 30 minutes and leave everything on except gestures (turn that off; it's nice but drains the battery fast). Tip: the device is fully charge when it been ship but after 30+ days in transit, expect the battery is not fully charge even so it say 90% it still drained. my sudjestion to use let it draid until 20% and chrage it this will let your battery last as per stated of the seller. Overall, I recommend it.
