I've owned this set of long-nose pliers for 4 or 5 years I think, and they replaced a set of pliers from another company that literally snapped. The DeWalt pliers are of far better quality, are much stronger, and are very, very comfortable in the hand. However, not all is perfect: this locking mechanism is not designed well at all. They may or may not open with the slightest bump, and there's no way to fix it without grinding down the silver lever a little bit. You'll see in the photo they're slightly open; they open very slowly until they pop open all the way. These were in a drawer when they opened one time, and it prevented me from opening the drawer. I had to get my daughter with her tiny hands to reach inside and move the pliers. Pretty frustrating. If they redesigned the silver locking lever to actually catch like it should, this would easily be a 5-star tool.
