Let me try to use it in a sentence: I occasionally exasperate myself when I consider investing on a PC with ISTA.

Currently, I have my X5 and family members' e46 and e90s running well without CELs. Though, they have some errors like light bulb warnings and sensors throwing codes.

I'm been using iCarly on my phone. When I had the paid $50 subscription, I was also able to code a few features like navigation warning off and folding mirrors when locking.

For now, using icarly as an OBD tool is working fine. It can also pull info like fluid temps including the transmission and coolant. It helped me out when it gave me a specific code for a slow pumping water pump on an e91.
