Look here how users think of them:
1
vvdi mb can renew esl, cgdi cannot
2
not work at all. buy vvdi mb and u will be happy
3
I think, you should buy Vvdi prog too, because the are some eis and ecu's that you cant do with MB Tool independently. For example some w210 eis or Sprinter 906. I have both, MB Tool and prog. If I had to buy some tool again, I would think about Simone Touch, but its more expensive.
4
making keys is not my main job and I would like an intermediate tool that does its job well without claiming the impossible. and that it has an honest price for the use I would make of it
5
bought a cgdi, not working yet as it needs activating, didn't see the small print that you can only code a certain amount of keys for 6 months before starting to pay!
service is really crap from the supplier as well but I wont mention names!
6
the cgdi works ok, programmed various keys and 2017 sprinter
7
VVDI MB is original device of which have made a copy and that is CGDI MB
