B-Grade I think has 90 days with OcUK
What does "B-Grade" mean?
B-Grade items are manufacturer's repairs or items we are unable to sell as new, they may be subject to packaging damage or may be a brown box product. All B-Grade items come with a 90 day warranty and may be missing items such as driver CD's and cables. Unfortunately we are unable to provide you with the reason why this is B-Grade as each B-Grade item is different.
