The price is very reasonable, they are easy to work with (if you have any questions or issues - their support team will be happy help), there was no downtime in our certificate renewal process when we switched from GoDaddy certs to startssl's cert for same domain/subdomain names! They also offer EV Certificates which can only benefit your business if it meets certain criteria that I don't think apply here but would recommend checking out anyway as this may change things up slightly. Nothing really at all about STARTSSL themselves so far though just using them solely because of cost savings compared to other providers like Comodo etc who charge more than twice what START does per year ($10 vs $20). We've been able to save money by switching over without having an issue since everything works fine now.
