For a reputable purchase decision a dealer with high rating count and almost consistently positive ratings, a direct comparison with a verifiably genuine model and typical authenticity features like correct engravings and proportions speak. Discounts of twelve to sixteen per cent are usual on online purchase, but the manufacturer warranty and free nib exchange fall away; the two-year statutory liability for defects continues unchanged. An MB boutique is primarily a sales outlet and not an official testing point; only Montblanc itself (Hamburg) can carry out an authenticity assessment bindingly. Despite unclear roles of individual actors, it is in Montblanc's interest to take action against product piracy in online trade.
