Worthless product
I paid almost $2300 and my teeth are not in very bad shape. I was hopeful to get better alignment but I was mistaken big time. I used my aligners as described and I did not see much change. I contacted support. Support person changes every time. They sent me endless instructions and asked me send many photos. After all I dont see any visible improvement on my teeth. Dont waste your money. Just save a little more and get a treatment from an orthodontist. So, you can get real treatment and have someone talked to.
