Been using it for about a year... used the PTP2 previously. Never had an issue with it. The snap on tool box that comes with it is great for shops just starting out with reprogramming. Lots of much needed information that can be extremely difficult to find the first time round!
(iATN Note: At the time of review, this product was titled "Pass Thru Pro 3 by Snap-on").
For the price this tool is good. If you're a diagnostic shop I wouldnt recommend this to be your only scan tool but it definately wouldn't hurt being a backup or the tool you grab to pull codes for someone passing by. If you want more detail, feel free to contact me.
This tool is fast, well thought out and king of the diagnostic world. The speed of the full system scan or health report is incredible. Im not going to get into detail but if you're in the market for a new scan tool feel free to get in touch with me and we can chat.
