These pliers appear to be very budget friendly. They work well and if you come across clamps that require these types of pliers you'll be glad you have them. However, they are clearly not of the best quality. Tolerances are pretty bad, surfaces aren't well polished at all, and things just don't fit together very well. This would be good for a person who only uses it once or twice a year. If you are a professional mechanic who makes money off your tools every day, I would recommend a higher quality tool.
