Advantages of the device:
- Standalone
- Printers
Disadvantages:
- outdated
- unwieldy (the 1552 is significantly better in this regard).
Check the used prices on 3-2-1 (or other platforms).
Buy when a profit of 100-200 EUR (or more) is expected, with the intention of reselling it.
From the profit, buy a proper VAG-COM system - it's more up-to-date and can do more.
If there's still some money left, then invest in a small, lightweight notebook. Tablets, or those that function as both a regular notebook and a tablet, are excellent choices.
