The best thing about this software is that it's free, easy-to use & simple interface which makes its usage very user friendly as well! It doesn't have any specific feature but I like how bugs are reported by using their own unique ID for each of them so there won’t be much confusion while tracking all reports made under one account or project etc., also when you need help with your queries they provide 24/7 support service too (which i find really helpful).
So far nothing bad has been mentioned regarding my experience till now!! If someone wants an awesome tool then go ahead try out. You will love working here because we just get rid off our old system where everything was done manually hence saving lots time along side increasing productivity level at work place. !
