4.5 3m cable Delltrott | 05/04/2013 | See all Delltrott's reviews (1) Initially worked ok. Despite being careful with it within a week or two it started to work intermittently then after two months stopped working. Tried to get a replacement and told only guaranteed for 28 days. If I knew that I would not have bought it. Don't buy if you want it to last more than two months.
