Reports are split. With modern Delta models partly massive ink-flow problems up to writing unsuitability are reported; older pieces like the Delta Jubilee (lever filler, 18-carat nib, ink hose renewable if needed) count, by contrast, as on a par with the writing quality of a Montblanc 146 or 149. The Delta Dolce Vita also convinces in everyday use through reliable starting and clean writing behaviour. Overall Italian brands count as more design-bold and colourful but workmanship-wise more vulnerable than German standard brands; an experienced Delta dealer with working service is therefore recommended before purchase.
