Everyone's different I wouldn't work without it. I know it's not for everyone. You may be surprised, but it does sound darn strange don't it! I can certainly understand your point. I didn't go looking for it, it was for sale at the paint store I use to get all my supplies from, just a hundred yards from my shop. It was the only one they had so I bought it. I now have one at work and at home, I really like it.
