Review on VXDIAG VCX Nano GDS2 & Tech2Win: Advanced GM/Opel Diagnostic Programming System with WiFi Capability by Robert Larris

This diagnostic tool works great. A little difficult to set up. The work took about an hour and a half. Can't establish a continuous data connection on a p4, 1.6 gigabytes, 512 ram and 5 gigabytes disk space running windows 7 32-bit, keeps losing connection and every 10 seconds or so. So I tried my newer (looks like really old) Dual Core 1.6 Celeron, 4GB RAM, 500GB HDD, Windows 10 64. This tool works great on this laptop. I have a GMC Yukon XL and it can communicate with all the different modules diagnosing problems. You can also use the included software to enable I/O, reset and recalibrate various vehicle sensors. I've bought several different scanners and none of them can do a fraction of what this one is capable of. This is by far the best tool I have in my toolbox and this tool was definitely worth every penny (if not a penny). Shipping was fast paid for next day delivery ($7.99 I think), received it on Sunday. I definitely recommend this product.
