Bought this for an Arris freesat box. it's the same as the duff one it replaced. I suppose 2.5 years is a bit short a lifespan, but it does get a lot of use. If this lasts as long I'll be happy. Working well so far and if it is brand new as stated, it should continue to do so. You should beware that some are refurbished and I would not expect they'll last very long.
