Need a new scan tool

Well I know that action and innova made more than 1 model of scan tool.
Maybe yours is newer, maybe a different model, maybe I'm too used to the shop's OTC (outdated) or my snap on, as to why I don't like the innova I have. It don't do all that it claimed to on the package I do know that.
We have another one at work that nobody likes it's called auto enginuity or something like that. Has to be used in conjunction with w laptop. Neither the boss or me have been able to get that thing to do what it is supposed to, ever since new so that one just collects dust.
