Sibata Glassware: Good or Bad?

Hi There:

Anyone know anything about Sibata brand glassware? I'm about to pull the trigger on a set of pipette's under that brand name. The specs/tolerances look pretty solid on these pipette's, but as you know, not all glassware is created equal.

Pipettes are delicate as it is, and the last thing I want is the volumetric markings to start flaking of at the first exposure to a weak acid or something.

Thanks for your input.
