The Risks of Relying on Sync Services as Backup

For £52.32 ex-VAT, the Brother TN-4100 is a pretty sensible choice **if** you’re running a compatible Brother laser machine and you want something that’ll be straightforward: consistent prints, no hassle, and you’re not betting the office’s output on “compatible” toner quality. In day-to-day B2B use—standard documents, invoices, letters—it’s the kind of cartridge that tends to behave predictably, which matters more than squeezing pennies when uptime is the priority.
That said, I wouldn’t buy it just because it’s “original” if you’re cost-sensitive on volume. The real question is your **monthly pages** and whether there’s a cheaper high-yield option (or genuine price/performance alternative) available for your model. If you print a lot, cartridges like this can get expensive over time compared with better value options. If you print lightly or you need reliability for critical jobs, then yes—this is worth it; if you’re churning out high page counts, shop around before locking into this price.
