Best place to buy Nexiq USB Link for Volvo PTT, Cummins Insite, CAT ET?

For all people,

I want to buy communication interface mainly for Volvo PTT, Cummins Insite and CAT ET.

I have seen Nexiq USB Link 2 widely used for this application but i have few questions regarding their usage..!

nexiq-2-usb-link-with-bluetooth-1

1) For Volvo PTT 1.12 and 2.04 – do i need additional medicine to use Nexiq for Volvo PTT (cracked)??
2) Does Nexiq support all vehicle in Volvo PTT?
3) Does Nexiq support fully for cummins Insite ( Generator, Industrial Engine…etc??
4) Does nexiq support fully for CAT ET ( Mining Truck, Generator, Construction equipment..etc)??
5) Can I use nexiq for scania Truck??

Is there any other better option is there??

Nexiq Chinese clone vs Genuine which one is better??

best place to buy Nexiq?

A user review from chinaobd2 (just for reference):

i have Nexiq china clone for 4 years, and Tech Tool PTT 2.04 for 1.5 years. Both work no issues so far.

1. NO need additional medicine to use Nexiq for volvo PTT
2. PTT support new truck up to 2016, but Nexiq.. no joy
3. Nexiq support fully for Cummins Insite
4. Nexiq cannot support CAT with the CDL protocol
5. Nexiq cannot Scania trucks

never used genuine Nexiq… dont know the difference…chinese clone work perfect in my hands…but need luck i think. My friend has no luck with that…rework many times but still no joy.
i buy Nexiq from China OBD2 support wifi and bluetooth. the Nexiq USB Link 2 you mentioned above doesnt support wifi and bluetooth as far as i know.

Good luck
