Heavy and hard to transport, but other than that, it's on the scale of amazing. I fell on my neck from 12+ feet onto this pad and all I had was a headache.
It works well in the gym, and decent outside as long as you're not more than fifteen feet off the ground and you have no rocks under the pad. If you are using it for your primary pad try and find a place that has sand or grass underneath it so that the blow won't rattle you to badly.
These are super aggresive, if you're not into more technical stuff, then shy away. Don't get me wrong, this is an amazing shoe, but it may be more than what you're looking for.
