Reviews for DKN Fitness UK show a split between product performance and after‑sales experience. Multiple reviewers describe motor, belt or frame failures and significant difficulty obtaining spare parts or warranty repairs. At the same time, some customers report fast, effective responses and successful part replacements, sometimes via retailers. Consumers should check warranty length, spare‑parts policies and retailer support before purchase, and consider model‑specific feedback (for example motor longevity and app usability) when comparing alternatives.
