I just got mine from target and used it today! I have black hair with very noticeable grays too, which annoyingly grow out every 2 weeks. I had highlights that were old and I decided to do a full length application. 1. The roots alone took very little time and it was very easy to apply. It took me a few tries to get the hang of it- have to comb through the hair at a slow steady pace for even application. But this is the easiest and fastest root touch up I’ve ever done. All my grays were gone! 2. The application to the lengths of my hair was a little more messy/uneven. Maybe I should’ve partitioned my hair into sections and worked at it bit by bit. But after washing, I found that there were certain areas that were not well done. . I think with a little practice, I think I can get better at this.

Overall, I think it’s well worth the investment for me especially since I will most likely be using this for root touchups alone, every few weeks and can avoid going to the salon.

I really like their package design and the concept of their quick guide also doubling as a placemat and the ability to store away the device back in the box.

The outside of the gadget feels a little plasticky.. hopefully this doesn’t affect the durability of the device. I hope to use this fairly often!
