How to choose the best Kess V2/Ktag Master China Clones

There are too many Kess v2 and K-TAG master ECU tuning clones in China market,which one should you choose? In the following parts, uobdii.com provides you three 3 ways to pick up correct one.
Tips:
If you need fix/repair ECU, you need Ktag. If you want ECU remapping,you need both Kess v2 and Ktag.
Option 1: Check the basic information including version especially the hardware version, the tunning way (via OBD or BDM), the vehicle coverage, the language and if the price.

Option 2: Customers feedback reference
This table can only show the basic information; customer feedback on kess v2 and ktag is more helpful.
Customer Feedback on Kess V2 VS Ktag:
Kess (even china good clone)…more stable than Mpps on can-line and good job on recovery…
and best ktag-trasdata-no obd but safe boot mode,pinout direct conection and bdm…
KESS V2 is a ECU programming tool that is perfect for OBD use, while KTag is perfect for Jtag, BDM and all the Boot application (tricore and ST10).
With KESS V2 you programming directly through the OBD port of the vehicle, while with Ktag you need to take apart the ECU and open it, after you can make the read/write operation.
Many ECU has the advantage that can be read and write from OBD port (so KESS V2 is perfect), but there are lot ECU that need to disassemble from the car and open and this is the case for all the ECU that need to be programmed with Jtag, BDM and Boot protocols, so KTAG is needed.
FYI, the difference between master and slave version:
If you have master version you can work directly on the program you have write on the vehicle (tuning, egr off, ….) and rewrite after directly. If you are a slave custommer (who depend of a master (who do modificated), you read the programme (cripted by genius), you send it to the master, he do what you whant (money paid) and he re-sent to you to write in the ecu machine
it is expensive for the slave user who depend of a master.

Option 3: Check the PCB
From the PCB, you can judge KESS V2/KTAG quality.
Take the best selling Ktag V6.070 (SE80-C) and Kess v2 V4.036 (SE87-C) for example.

For other PCB, just browse www.uobdii.com and search KESS V2 or ktag.
