I like how fast it responds when you type something into an input box or select from options with drop downs menus - this makes life so much easier than having multiple screens open up at once just waiting while they load all those pages together which are constantly changing/updating information (like security passes). Sometimes there's lag time but nothing majorly bad about what i've seen thus far compared to other companies out here such has been doing business using similar systems since 2007+ now years ago before even google existed. Nothing really specific except sometimes typing things will take longer then usual if not done correctly due to speed difference between pc vs phone keyboard etc; however no big deal considering its still working fine otherwise & overall great product regardless!!
