Cela fait 5 ans que je collabore avec eux et j'ai toujours été comblé. J'ai commencé avec quelques articles en inox et maintenant ils ont refait ma cuisine en entier , assure mon SAV et les entretien. Top! A recommander les yeux fermés.

Service rapide et efficace. Je recommande vivement !

Äusserst freundliche und kompetente Beratung. Bin sehr glücklich mit der Auswahl von meiner neuen Brille. Danke an das gesamte Team!

Bin seit meiner ersten Brille vor mehreren Jahren Kunde bei Luxor Optik und habe immer gute Erfahrungen gemacht. Klar sind die Preise höher als einige der Mitbewerber, aber die Beratung ist sehr gut und die Mitarbeiter sind freundlich und kompetent. Der ganze Betrieb ist familiär, aber trotzdem fehlt es nicht an Professionalität. Ich kann mir jedes Mal sicher sein, dass meine Brille von guter Qualität ist und es ihr an nichts fehlt.
