As a hobbyist, I often struggle to find the right tool to complete my projects. However the Hot Max crimped brush exceeded my expectations. Industrial and Scientific quality at an affordable price. As a result of my tests, I determined that the brush is durable and long-lasting. The positive results in my final projects speak for themselves. The only con I could think of is that the bristles can fray over time, but this is a minor issue that can be easily fixed. Overall, I highly recommend this brush to anyone looking for a quality tool at a reasonable COST. .
