AI-generated summary
For £30.98 ex-VAT, the Kensington Pro Fit Ergo TB450 is a solid buy if you want a *proper* trackball for day-to-day office work and you don’t mind that it feels different from a normal mouse. Kensington’s trackball-style ergonomic approach is usually pretty good for people who get wrist/forearm strain from mouse movement—especially if you’re doing lots of scrolling and desktop work where a “stay still, move the ball” approach helps. In practice, it’s the kind of mouse you either instantly like, or you spend a week getting used to the aiming and clicking habits.
That said, I wouldn’t recommend it universally. If your workflow relies on fast pointer sweeps (design work, certain CRM systems with precision clicking, rapid drag operations), the trackball learning curve and movement style can slow you down. Also, trackballs need occasional cleaning—dust and grime build up in and around the ball—so if you’re in a shared, messy environment, plan on maintenance or acceptance. Overall: good value for a UK office environment if you’re specifically trying to reduce repetitive strain and you’re happy to adapt to trackball control.
If you tell me what your users do (mostly admin, CAD/design, spreadsheets, lots of scrolling, etc.), I can say whether this is likely to feel like a win—or a needless “ergonomic” compromise.
