It is most definitely worth the money. If you havent tried it go to MaryKay.com to find a consultant near you. She will let you try out the mascara for free (and any other products she has). If you dont like it theres no pressure to buy. Plus MK consultants can give out huge discounts so I would recommend bringing that up to her as well!
Honestly, if I could recommend to you, try the Essence brand mascara... It is in a pink tube called "I ❤ Extreme Crazy Volume." It's only $6 and is MUCH better than all the expensive brands I have tried!
