They're a lot smaller than most of their competitors (that's why I bought them) but the handles are nice and thick and they seem to be more durable than you might expect. I like that they have a lock unlike Hakko CHP-170. The Hakko keep popping open making it difficult to close my toolbox, but they stay closed and don't give me any trouble. If space isn't a concern I'll probably stick with the CHP-170, but for my drawer where space is critical they'll definitely help.
