not really too great on Staples anymore after purchasing some ink for my computer one ink the clamp that holds it in securely was broke took it to my local Staples Store and guess what? Walked out with the broken one no replacement no ink all the years I have purchased items from them makes me quite SAD
Worked for what I needed. Improved keyboard performance by cleaning out some gunk. May have to replace keyboard however since I can't remove keys to clean.
