These are durable and well made. I especially like that they're designed to not only pull, but push the springs as well. The different angles are helpful for different spring locations, too. The only knock would be that the paint gets scraped off easily in normal use. This wasn't a surprise, but the finish would be more durable if they were powder coated instead. Great product overall.
The spring tools are well built and far better than vice grips and screw drivers. The paint does chip off easily but is of little concern. Having multiple tools with different lengths and hook configurations makes this a great buy. The other nice feature is having the additonal notch to push springs into place. Great price for 5 spring tools.
