Just got it; it seems great!
I've only had my Cubii for a few days; first, I have to say that I'm the least handy person in the world, and I cannot tell you how much I appreciated the easy, clear instructions on assembling the pedals, as well as the carefully packaged screws--it even came with its own screwdriver! I hurt my knee a few days before it arrived, so I've been just using it gently, but I'm very happy with the purchase.
I suffer from severe Restless Legs Syndrome, and it was my neurologist at the Sleep Clinic who recommended I buy a Cubii--her other patients have found it helpful. So when the restlessness gets really bad, I use the Cubii and my legs settle down--the restlessness can be really unbearable, so it means a lot to me to have a way that I can help the symptoms. Thanks so much!!!
p.s. to have a company that actually has accessible customer service is beyond delightful! xoxo
