Customer comment
Been working with Sigma for over 4 years, Sigma always perform very well with quality which I’ve never worried about. They response as soon as they could for any unexpectedness , and solve the problem at the first place, they show their sincere attitude with speed , this is very commendable and hope they could keep it.
”We start to have bussiness with Sigma from 2012 with sopt buy bussiness, they were doing well from no matter response speed or price, there were even some of the spot buy price better than our normal lead time price. So we start to try them with lead time projects from 2014. It’s been 3 years till now, we now have over 70% bussiness as lead time buy projects with Sigma. I trust in Sigma,because they are doing well in price, lead time and quality.
”From one of my friend I knew Sigma, because we started our Jiangsu factory in 2015.It was in last year after auditing in their ShenZhen office I approve them in ,in the same year they made good contribution to three cost down projects in our Jiangsu factory. By the end of last year I leaded them into our European headquarter site, and they performed quite well in quarterly cost reduction from this March.
