Calculation Password always the first time, never fail.
6th November, 2017 feedback:
Yesteday test online calculation, very fast, less than minute. And the counter (10) decrease to 9.
Today it become 10 again. So i think for now until 6 months, i can calculate 10 time/day.
12th November, 2017 feedback:
Test with my W209 545 31 08 on bench as add key: 15mn all done
Trying all key lost, failed. But a friend do with W209 545 05 08 success PSW by IR without gateway
Many thanks for his feedback, he even promise when he has news he will post.
In addition, CGDI MB tokens:
This device also work with tokens for password online calculation
Here is info from dealer about token for CGDI MB:
free token half year, after that it is free in each day, if u calculate more ,than need to charge 8usd for 30times and 16usd for 60times. Also all key lost need ONLY 1 token.
Conclusion:
CGDI MB need improved function and report what work and not for now in this device.
CGDI is new tool, just come to market less than 3 months, what I can see in video and some users posted, report back successful: For me it’s good tool and have many good future.
Even VVDI, and others (more expensive price) have problem when beginning and still have too. The most thing that many ask for is: Absent clearly manual to work correctly on bench: All key lost.
This tool is the best investment return for now even with youth problems.
Thanks to users’ big support, your encouragement is the driving force of CGDI.
