Stuck on blue color after 6 months

unable to change the colors after 6 months. not recommended. I am happy to update my review after I contact the customer support to see what my options are. Edit: contacted ustellar for replacement. They gladly approved and told me they would ship me 2 new units in 15 days. After 30 days of no sign of shipment I contacted them and they told me these are out of stock. Still trying to figure out a solution. I will update this review again. So far terrible experience.
