i experimented with it a little the other day but didn't use it to decorate anything because i couldn't get it to roll out without sticking to EVERYTHING. i think i'm going to try using it to fill some chocolates instead 
this probably wasn't much help...but good luck!
I used rolled buttercream on the grill cake that is in my photos. It was easy to work with and was just like playing with playdoh. My daughter helped make the items on top of the grill. The grill itself is covered with rolled buttercream.
I will use it again something.
darandon~ have you used mmf before? If so, how does this compare? Did it dry fast as far as the molded things on top?
I ended up making the rolled butter cream because I couldn't get the MMF to turn out right 
the RBC had a texture like fondant, but did not become hard. It was firm, but did not get hard if that makes any sense. The hamburger and hot dog on my grill cake were soft enought that the kids all tried a bite of it (yuck too sweet), but it did not stay too soft that it was sticky or anything like that.
I made RBC, and I only have a hand held mixer. I found RBC to be a little more difficult to work with than MMF because it doesn't have the same elasticity or flexibility. I ended up rolling it out between parchement paper sheets because I had trouble with it sticking too. When I covered a cake with it, it looked bumpy at first (like large air bubbles underneath), but I took a pin and inserted it at an angle in the air bubbles and they dissappeared. I had to work with it a bit after putting it on the cake to make it look smooth, but it ended up turning out pretty nice. I used it for my "embroidered cake".
Thanks for the bumps and replies!!! I will try it with my hand held and see how it comes out.
Jessmar - I think your cake looks great! It looks very smooth from the picture.
Darandon - I love your grill cake too! Did you dye that with color or were you able to use dusts on it?

I colored the "food" with just regular icing colors. The grill I used a spray black (which looked more grey than black) on it and dusted it with a bit of silver to make it look metalic. It looked great in person. I'm glad you liked it.
