I've got two diff RocketBooks , one is paper (the "microwave to erase") and the other is the Matrix ("wipe with moist cloth"). I love both of them. They make writing, capturing, and erasing super easy. The "Wave" is a paper notebook, and is less likely to smudge, works really well with color ink, and has a nice feel. It has durability problems, though, and the front and back covers are both tearing off. I actually glued them to the first and last writing pages to reinforce the binding, and that's working fine. The ink "shadow" tends to build up over time, and not fully erase, even with vigorous rubbing with the pen eraser or excessive microwaving. Also, it's paper - pressure lines accrue over time, also. Still, it's an awesome book. The "Matrix" is a lot more durable, since it's basically plastic. One weird thing I've noticed is that rubbing it with an eraser seems to damage the surface, and it's building up...
