Top home improvement Easy to use, smooth and stable than expected. I have less quality expected at this price. Above all, I am pleased that these terminals remain not depend upon release, as so often experienced in others. Easy to handle alone. The material saver fulfill exactly its purpose. Home improvement recommended. How it looks with the durability I do not know, they look very stable but it's just a lot of plastic off, where I see any danger of breaking in permanent use / aged.
