I purchased these because we just bought a new house and new house means lots of painting! This is our third home we've owned so I have painted a lot over the years and have used a good variety of brushes. For the price, these are phenomenal!!
They aren't perfect, a few bristles come out when you are washing and if you are edging out a whole room they tend to get a little goopy by the end. By that I mean, they accumulate paint on them and the paint dries a bit as you're going along so by the end of the room you need to use a little finesse to see that your edge is still clean and straight. Though, that said, you get 5 brushes!! So if you are finding it difficult to get a straight edge because of the brush getting full of paint, just grab a fresh brush.
I find cleaning them easy. Whatever the bristles are made from cleans off easily with a small bit of soap and water. Aside from the few bristles coming out I have no real complaints. I have washed them all multiple times already and they are still in great shape. These will definitely suffice to get me through all my house painting and I believe they will hold up long beyond.
I would absolutely purchase these again and I would also highly recommend them.
