AI-generated summary
The Brother TN-3390 (original) is a sensible buy if you’re using a compatible Brother mono laser and you want consistency—clean text, reliable starting each time, and fewer “mystery” print quality issues compared with cheaper third-party options. At £122.65 ex-VAT, though, it’s not what I’d call budget-friendly, so the value really depends on how often you print and whether you can reliably match it to your specific printer model. If your machine is kept busy and you go through toner regularly, paying for the original makes more sense than gambling on off-brand performance.
I wouldn’t rush to buy this if your usage is light or you’re cost-sensitive: at this price, even small inefficiencies (like occasional heavy cover printing or leaving the printer to sit unused) can make the overall cost per page creep up fast. If you print infrequently, it’s usually better to run the numbers on total cost per page with your actual print volumes—or consider a compatible/twin cartridge only if you’ve previously tested it successfully in your exact printer. Bottom line: buy it when you need predictable results and you’re printing enough to justify original pricing; skip it when you’re chasing lowest cost and don’t print much.
