After reading many reviews, I had originally decided upon the Innova 3160B. That is until I saw that the Actron is exactly the same as the OTC brand which appears to also be related to Bosch brand, so I changed my mind at the last minute and bought the Actron CP9580A. After reading so many negative reviews, I will admit I was reluctant and worried I might be buying a problem.I took delivery on my Actron yesterday, spent that evening reading the manual and connecting to the internet to try and update my programing. I read where the OTC website is the place to update, so that is where I started. I want to say that my office PC is running Win7 Pro and it would not change the programing into Actron and load on my Scanner. So I tried my laptop, which is also running Win7 Pro (both are 64 bit) and although it would load on my laptop, it still would not recognize my scanner. So I did what only other choice I had, go to Actron's website and see if it would work for me. On my office PC the program (OTC Scanning Suit 4.0 or Actron Scanning Suite 4.0) would load, but not setup or be recognized. Once I downloaded the Actron version onto my laptop, it fired up immediately, setup and recognized my scanner immediately also. The updated software was downloaded in 8 minutes (I also have the fastest download capability my ISP offers at 50mbps). Once I attached the Data Link USB to the scanner and laptop, it recognized the scanner immediately and asked if I wanted to check for updates. I said "Yes" and within a the 8 minutes, it was updating my scanner. Once finished, I disconnected my scanner and turned it back on to see what program was now loaded and it read "SW ID: 6A4D) the newest and most current software is now loaded onto my scanner.I took the scanner out and tried it on my 2000 Mitsubishi, my 2008 Ford and my F250 Diesel. It appeared to work flawlessly. I am completely happy so far. After I've had it for a month or so and no problems arise, I will change my rating to 5-stars, or possibly down grade it is things start acting up in a negative manner. I do not know what or how the people that gave this scanner bad reviews did, but the setup and update process through Actron worked perfectly with no hassles or delays what so ever.I bought the scanner without the plastic hard case, only because I didn't see $40 bucks for a plastic case. However, I am very careful of my stuff, especially electronic gadgets. I don't drop, throw or misuse or abuse them. I keep them in a drawer with my other electronic automotive tools and if I won't need it for a while, I remove the batteries. To me, common sense prevails on the longevity of anything type of tool. I did download the .pdf manual and loaded it on my laptop and my office PC, so I can learn more about it either in the garage or in my office. I bought it for my Diesel, because my check engine light keeps coming on and I really don't want to pay the $800+ to have some clown replace the ICP (Injection Control Pressure) Sensor when I can do it myself for under a hundred dollars, including the part. So my scanner has already paid for itself.It may be a little early to offer a really good review, but after everything working out so smoothly so far, I wanted to share my first impressions. As of Day-2 of ownership, I am a happy camper! To Be Continued!
