Surprisingly Impressed.

Have a Diamond 580 with a 1.1mm. We didn't have a great start, TSWBI resolved really quickly and loved it since. The ECO is great from the start. The 1.1mm is a little finer, probably not as smooth as the 580. That said, the simplicity of the design and price makes it a complete winner! More importantly the service and delivery is impressive.
