Comments about SPIKED
Been a MAC customer for 20+ years. Had my products professionally chosen by a MAC designer at a Macy's store. Loved what was chosen and used it since that time. Then all of a sudden, someone thinks it's a brilliant idea to take a standard size brow pencil and make it into a 1 mm size. For someone who went through chemo and never had her brows come back to normal, it takes a whole lot of pencil to make my brows look normal. This new design is horrible for someone who needs to use a lot of product. It barely lasts a month whereas the previous design lasted several months. Not only does this cost me a whole lot more, but using all these pencils and disposing of them is not good for the landfill. Unfortunately, I will have to find an alternate non-MAC product. I wish manufacturers would think about the entire population when designing a new product rather than what might be "hip" in the moment.
I would NOT buy this again
Constantly breaks! Only last 2 weeks! The old formula was great I've been using this for over 10 years I cannot believe make changed this to such a poor product. DO better MAC!!
I will not by this again
I have used this product for over 10 years. It is just awful now constantly breaks and only last about 2 weeks. MAC should be ashamed of themselves for cheating customers. This product go back to the old formula. I going to quit buying it DO better MAC
Best brow pencil for me
I finally found a brow pencil that defines my brows by shaping and filling the bare spots while looking natural.
