In Musewearables Reviews 

Ring is digging into another fingers, Loads of promises none delivered. Shows BS values. Took years to deliver the ring. Feels like scam

The quality of the ring is very bad. The material colour worn off within few days and the support is so bad that they dont care about the product and just wants to make money. Outside, the showcase all the functionalities to make profit but i reality nothing works as good as a ring that you from amazon or aliexpress

Very poor tech company that deliverers hardly useable products, often YEARS after the order has been made. Features do not match the features sold. Horrible company.

Muse Ring One was an indigogo campaign that missed the mark by making so many promises they couldn't keep. Began delivering the ring more than two years after initial promise while hacking out key promised feature that we're the reason for many to back the ring. They removed the following promises. Worlds most comfortable ring although in appearance it is stylish due to its raised sides it digs in to neighboring fingers. Rotating bezel to start activities and initiate nfc payments doesn't exist. World wide nfc payments nope not true mainly EU. Haptic feedback option, removed.. Sleep Apnea features, vaporware. On top of that the titanium ring had color options that appear to be paint that just chips off leaving an ugly ring after wearing it for just a few weeks. Lie after lie telling backers shipping had begun 1.5 years before it actually did and has stopped giving the promised perks to backers. This company after asking for forgiveness and understanding just lays down more lies immediately after. Avoid if you value your hard earned $.
