Review: Quality pliers for the price - A good tool for the price. Easy jaw shifting capabilities and good tooth hardness. This tool should serve general applications, I cannot speak for those demanding situations where ultra gripping strength is required. But for the price, it has proven to be a good tool.
Review: Great little pliers ! - I’ve use a lot of the smaller pump pliers and these are by far the most versatile. Use daily in a professional plumbing setting
