Promethean extended warranty: worth it or not?
OK, so I'm 2 weeks into my new NM position and have just been passed a warranty renewal quote for the Promethean boards at the school. Normally I would dismiss this without much hesitation; at my last school we used all Promethean and the only hardware faults we ever had were the PSUs. However, I'm making a point of revisiting my own past policies in my new role to ensure my own thinking is sound and not just force of habit. Therefore, I'd love to know what other people's thoughts on this are.
The quote for 2 years extended warranty is £225 per board. I'm not convinced that the average failure rate is going to make this cost effective. In addition, I'm actually not very fond of Promethean boards and prefer the SMART ones we have, so if one packed up completely (which I've personally never seen happen) I'd be quite happy to replace it with a new SMARTBoard.
