Legit Techstream License?

Hey all, wanted to do my own zero point calibration on techstream. Maybe a couple other things like tab’s and what not. I’m trying to get ahold of a copy of techstream, alone with an adapter. Just wanted to ask, is a 2 day license from this link legit? It seems like it’s official, but I just wanted to ask some of you guys. 25 bucks for 2 days is cheap and if I could do that myself it would save me some money. Even though the dealer did it to no avail. Would this work? Would the 25 dollar version allow me to perform said zero point calibration or do I need the 70 something dollar one? Thanks.
