As for the construction quality, it is very good and lightweight, so it doesn't tire your hand when you use it. I also really like the handle of the pliers and its insulation. I don't give them five stars because of the two flaws I found. The first flaw is that when you close the pliers, the cutting points do not completely touch, meaning they don't close completely so that light doesn't pass through (it seems due to a different design and mechanics of the new model from the company). The second flaw is that in the previous model, the jaws of the pliers had a larger opening than the current one, so you could remove the plastic if you wanted, to have it closed without damaging the plastic, unlike now where it is constantly open. Personally, I would prefer the previous model that I had, compared to the current model that I have now.
