This product has the pink tint removed which is the main ingredient to tighten under eyes. Very disappointed. I will start looking at other products. This is the 3 red time this has happened.

So its top notch quality except for a few minor details. A. It's a bad height. At its maximum height I have to do a 90 degree bend over for it be anywhere near sound projection placing, sitting down. It's not tall enough or can stand in a way to put on a table. I mean its inbetween knee and hip height. It's weird and I didnt expect that. B. Its legs dont seem to hold in any position but completed extended flat which means they cant help the height issue. C. As soon as I put a microphone on the thing it started to topple. It cant handle the weight of a single microphone. In any position, I had to put weights on the other side of it to counterbalance. ... that being said the parts look very sturdy and everything connects well and I doubt the stand itself will ever break even if it falls down a lot. So that's good.

I purchased these for friend who has been traveling. The headphones arrived faster than expected and came in their own zippered case. As soon as I gave them to my friend she was overjoyed with them. The case will allow her to keep them in her purse so that they are available at any moment. She has told me that they work great with her Google phone.
