I think they look pretty bad ass. The people who I smoke with/know I smoke thought they were bad ass. I use them as bartering chips to get free weed from my one friend.

For the ease of rolling, I never have to roll (never have either...long live bongs!). My friend that rolls them didn't have any trouble, I sat there and watched her one day. They look pretty neat. They burn well. They do have some resin build up after smoking for a while.

MAJOR problem with them - We were sitting in my friends truck with a half of a clear joint we had smoked a little earlier. We lit it and when she passed it to me, it went out. I relit it and it CAUGHT ON FIRE! I was high, so I just starred at it and said, "Dude?!!? There's fire!" It made a big, giant flame! That freaked me out a little bit. I probably won't smoke them again. It left a weird taste (that same joint) before it too.
