It's exactly what you would expect. This one is comfortable to hold, and relatively pliable, so you can bend it to break off old filler. It comes out of the box with a very smooth surface, so grooves, and filler building up over time really aren't much of a problem. 5 Stars: I love the thumb hole and etched out corners that allow you to hold it like an artist. I didn't realize how useful that was until trying to use Bondo and Fiberglass resin. This way you don't have to move much to reapply more product (ie. it doesn't overspray from your tool) 5 Stars: I believe that if you are planning on doing some body work this mixing board is a must, sure you can use something else, but i believe the right tool for the job is a requirement.
