The customer support is excellent, they are always willing to help you out with anything that comes up as long it's not related directly or indirectly (in any way)to their product/service - which was really helpful when I needed some assistance in getting my certificate into production! They also have an easy process for generating your CSR so there isn't much room left of guesswork here either if someone else needs one later down line from me :) There were no downsides at all but maybe more options would be nice like other providers offer? Maybe add something about pricing too since we're talking startssl price comparison vs others prices ;) Great service overall though very friendly staff who will do whatever can get them done quickly without asking questions just doing what has been asked by customers before :).
