I agree with the other posters that any direct sales/network marketing is what you put into it. I actually have been involved in a couple myself and have had had experiences with many others.
Now having said that, as a customer/client, Mary Kay left a bad taste in my mouth. At least in recent history.
I used and LOVED MK products for many years! But there was always the underlying pressure to 'join' and sell. At one time, I seriously had MORE product than my rep because she kept inviting me to 'meetings' and giving me free 'gifts' in an attempt for my to sign up. That was when I was probably late 20's early 30's. *I am now 48 almost 49.
Once I hit 40 though, my body chemistry changed and I found I could no longer use the products for a variety of reasons. About 3 years ago a friend invited me to a Mary Kay product demo. With apologies, because she herself felt like she had been strong armed into having it. I went and actually found some products I really liked! BUT when I had "my" time with the MK Rep and I told her up front but in a nice way that I will not sell and I will not have a party/demo, but still ordered $300 worth of products, I never heard from her again! She already had the pink caddy so I guess because I was not worth her time to follow up and keep as a customer, I was scum. Really? I'm not worth having just as a customer if I'm spending $300 a pop because I won't help you get to your next level? In my opinion, you're in it for the money not to help others.
When my daughter turned 15 last year I wanted her to learn how to apply make up in a tasteful fashion but would NOT contact a MK rep. I absolutely did not want that type of hard-sell person in my home! I found an amazing young woman who actually developed her own line of cosmetics and was thrilled to show my daughter and her friends artful and tasteful make up application without worrying if she would get a sale. She did it because she loved and believed in what she was doing. And in my opinion got a $700 in sales because she was so low key!
I also now am very concerned about the chemicals I put on my skin so I look at things differently.
