Here's customer suggestion on which tech2 clone should you get:
http://www.obdii365.com/wholesale/gm...d-tis2000.html
My buddy at the Chevy dealer says theirs is also at v.33.004
The one on aliexpress didn't mention any designations such as -B, -C etc. (or part number at all), so at that price it may likely be one of the cheaper hardware versions, which steered me towards obdii365.
They also had this on the site to explain the differences, plus another vendor confirmed the info in an email request I sent out yesterday:
Tips Help you choose suitable Tech II:
There are 5 configurations of Tech2 on our website, they are SP23-B3, SP23-B, SP23-C and SP23, SP23-1
All of them have the same function, their differences are :
SP23-B is the best Tech2 with Black Carry box, more stable
SP23-B3 is the SP23-B with carton box and best quality
SP23,SP23-C is the same as SP23-B, it also includes the Black carry box, but comes from another manufacture.
SP23-1 is the most cost effective one, it is with carton box, will help you save much more money.
In conclusion:
If you need the most professional Tech2 with best quality, please choose SP23-B ,because it has a black carry box.
If you need cheaper Tech2 with best quality, please choose SP23-B3"
