Lamy reacts on nib exchange even after several years often very accommodatingly, with free nib exchange and return shipping and short turnaround times of a few days. Sanford as a service partner for Waterman is by comparison significantly slower, because the writing instrument goes to France for processing, but is regarded as very engaged and customer-oriented; enquiries are recognised after brief name mention, and special requests are processed even outside the usual working hours. With Waterman the selection of nib widths is, however, limited, so very fine nibs (below F) are not available. In sum, Lamy is perceived in service as above-average fast and generous.
