Its never lazy.by Wade Bieber on 03/21/2017
Got this about 4 years ago, and love the functionality. It is great for multipitch when you might have to pay attention to many other factors on the wall. I even use it for sport, just make sure you know what you are doing. Read up on the Petzl approved belay method, and stick to it.
If you practice, it works exceedingly well and is efficient.
I think that this is an important piece of equipment that you should have if you can afford it. And you should make an effort to afford it.
