Top kwaliteit - alles zit er bij :-)

Dit is echt een prima gebruiksklare set. Er zit zelfs een batterij bij. Heel handig dat alles in een koffertje geleverd wordt. Dan heb je altijd de complete set bij elkaar en raakt er niks kwijt. Het is een degelijk apparaat. Goed display. Gemakkelijk te gebruiken. Er zit een duidelijke handleiding bij.
