Sorry but I didn't find this helpful at all. It provided non valuable minimal repetitive information and was about 4 thin pages. I'll do my own research trial and error in the Hope's I can get some positive credit union results.
negative

The brushes have good quality. They are soft, strong and easy to clean. It is good to have a lot of different brushes. As a beginner, I’m very happy with my purchase (I know they are all useful, I just need to learn how to use them all).
positive

I suffer with chronic pain especially in my neck and back. I have tried every kind of pillow out there only to end up with more pain and suffering. I slept on my new pillow for the first time last night and it was the BEST sleep I've had in a really long time!!! I know it has only been one night and maybe too early to review it but that one night made quite an impression and I'm looking forward to many more nights like it!!!
