Powerful scanner for a small price
After good and quick advice via Whatsapp, I chose this scanner.
While I initially thought this was too simple a scanner, it covers with the clear app all the functions that a more expensive device also has.
Easy to connect and pair with your phone.
Krachtige scanner voor een klein prijsje
Na goed en snel advies via Whatsapp gekozen voor deze scanner.
Waar ik aanvankelijk dacht dat dit een te eenvoudige scanner was, dekt hij met de duidelijke app alle functies die een duurder apparaat ook heeft.
Eenvoudig aan te sluiten en te koppelen aan je telefoon.
