my girlfriend and I get a matching pair of these when we start date a year and a half ago . they have hold up beautifully despite they daily beating over the last 500 + day . definitely solid . and I \/ we love the wave design - it be clean , pretty , and I really like the subtle clever use of negative space for the oppose wave . like the ying and the yang . my only complaint be the welding on the outer spinning band . you can not see it in the picture , but where the outer-band be weld together , there be about 3mm of welding material , cover a entire wave , and it look a mess . fortunately , it be smooth and do not really bother I that much . I be spin it around most of the time anyway . and it be not like this be a Tiffany 's ring -- for the price , it be really hard to complain .
