I'm only demoing it, but after checking out dozens of other highly rated services I'm going to give it a 5 star because the features, visible layout of tickets, clear readability of ticket threads, and color coding high lights make this plat form one of the best I've looked at for the money.
Pros: great user interface. highly task focused without a lot of other distractions. color coding of open tasks and viewing of message threads is wonderful. Price is about the lowest on the market.
Cons: public customer site is a pretty basic. after working with it for 15 minutes it crashed and I could not login again. sent a request to support desk.
We've been using ihelpdesk for about half a year and so far so good. It does a good job help us track issues, and make it easier for us to provide excellent customer support.
Pros: easy to learn and use. good usability. rich features.
Cons: we need iphone client but it's not available. raised a feature request to them, hope it will be available soon.
