Mack offers extended warranty for a variety of products. I happened to buy one for my laptop about 3 years ago. I had a keyboard problem with my laptop as soon as i bought it...but never had the time to visit the store to get it repaired...
Finally when I got the time to visit the Mack warranty store in New Jersey, I found the customer service was poor, they seem to be looking for reasons to reject the warranty coverage... The person who spoke to me at the store appeared to have no intentions to get the laptop fixed under warranty.
He was blaming the dirt in the monitor, and normal dirt in the keyboard as reasons for his refusal to cover under the warranty...
I'd never recommend anyone buying their warranty...
