I like how easy it was to set up, even with my limited tech knowledge! It has made submitting RFI's much easier than filling out paper submissions or using excel spreadsheets; plus we can easily keep track of responses from vendors in one place instead of having them all scattered throughout our office space (like at work).
Nothing really - just that there are certain features they could add which would make things more user friendly for people who aren't as familiar w/ computers etc., but otherwise everything works well enough so far!! We've been able t get any new equipment without first going through an RFQ process where you have a lot less control over what gets included vs excluded when compared w other companies' offerings.
