Hello, I am a garbage owner, I am searching a good digimaster3 for my Inc, I want to use on many car models in different years. But after looking on your website, I have some questions:
1) We find that you have many mileage correction tools. Which one is best?
—Yes, we have many kind of mileage correction tool, like: digimaster3, tacho pro and digimaster3. The best mileage correction tool is digimaster3, original and can work on almost any cars.

2) I searched on your website and found that there are two kind of digimaster 3, what’s the difference?
—-Yes, we have two kind of digimaster3
One: digimaster3 ( SP78-B), the other is : Ordinary Digimaster 3( SP78)
Same: the two items are the same in function, they both can work on most cars.

Difference: Digimaster 3 with 1180 Tokens, work on car by using the tokens, that means every time you work on car, it will consume some tokens, and if the 1180 tokens is up, you need to buy the tokens in order to working as usual. But the other kind of digimaster 3 work on most cars without consuming any tokens, that means you can use it without time limitation.

3) But now I find that your digimaster 3 is also with 200 tokens as gift, why need token?
—-Yes, as we say the digimaste3 can work on car without time limitation and token, but if you want to do some newer cars, like: 2013 cars, or some luxury car, you will need tokens. Now we are on promotion, you can get 200 tokens as gift( Before we don’t have the token for you) . In a word, digimaster3can working on ordinary, luxury, and newest cars.
