Buy a lot of tech and want guaranteed coverage, look no further.
The plan was very much worth it. My son's monitor went out for the 2nd time, the first I dint have insurance, and I filed a claim and got the whole amount back after it was determined it could not be fixed. All this process took no longer than one week. Grateful and will definitely but for future purchases.

Great Color
Size: 1 Count (Pack of 1), Style: Cartridge Ink
I was hesitant on purchasing this item. My skepticism was relieved when I installed and printed the first picture...very good quality. However, seems like the ink supply went quickly, either not a complete cartridge or I print too much(which I don't).
