This electric pliers is really very good. They are black anodized aluminum for wear and cosmetics. The swivel is well designed and strong enough to provide good leverage, it's very easy to handle without sticking, and it's also durable. The included replacement pine inserts are scratch-resistant and soft, but the high-hardness material should last. The length of the tongs could have been a bit longer for my caveman hands, but it's not too short. Jaw opening range is sufficient to grip a variety of sizes. After using them I found that I really like them. If you don't already have these pliers, you should try them, they are very useful.
