Currently I bought a lens pen from BestBuy and it really make my lens dirtier. . .Oh gosh so frustrated.
I thought lens pen is the best practical solution to cleans the lens.. ..
Which product should I use instead? I need something very practical and convenient. Now I'm so frustrated whenever I saw something about BestBuy and to look at my camera. HUH. . ?!!!

Some items can be found that are good but few and far. Don't buy items to clean expensive gear at bestbuy. lol sry but its the truth.
