In a production environment working 1 shift 5 days a week you get at least 40 hours of iron use per week. You need a new tip for every iron every month or so with 200 hour life. Usually this is not something the bookkeepers will take sitting down for long. Especially if the tips have a price tag like the Metcals. But maybe others think differently.
