Cover Girl Very Black Eye Liner Stick Review

I don't understand covergirl. I use their covergirl perfect blend eyeliner...black. I think it works wonderful. I have been through the 1980's with all the make up and all the really bad eyeliner that you would have to set on fire to work! I went through many different brands and types of eyeliners, a friend of mine had this one and it went on so easily I loved it. I started buying it all the time, even though it was a little more than I was used to spending..but it worked wonders. I loved it. Well when I went to the store I could not find the perfect blend so bought another covergirl black eyeliner. I could not believe how awful it was!! This was the same company making this eyeliner? I still have those eyeliners and would like to write covergirl and say why is one of yours so wonderful and when they didn't have it and I buy another one of your brand it is awful! I have not though. I had to wait for the store to get in more and go without eyeliner...oh no....and then get back the good kind!
