1 month ago I went to Megabox showroom and asked if I would have a demo on E600 and C2420/A46 in any one of their showrooms...The staff there replied me very nicely, politely & seriously that "I would give you our back office number and they would help to arrange the demo in either one of the shops in Yau Shing"
