Their expertise in Salesforce is unmatched as they have helped us solve complex business problems with our SFDC implementation that we were facing before working w/ them (2+ years). They are highly responsive & deliver results every time! Nothing to dislike so far!! But if you want your data stored securely then go for it. Highly recommended!! We use WLrE mainly because of their knowledge about sales force automation products like CRM's etc which also gives me peace-of mind knowing my organisation will be using appropriate product when I move out!
