The best feature i like is its ability for fast searching of packets with filters, you get results very quickly. I dislike that it's not free as we are using some other paid software so need extra money from our customers if they want us support their tools too! It works great but sometimes slow or hanging up when filtering huge amount of data. There isn't any problem by now only minor bugs here n there have been fixed recently. Packet sniffing & analysation tool helps me solving technical issues related networking problems without having much knowledge about these fields.
