“The staff here at Brooks Dental enjoys the ease of use of the PowerScrub VLC when flushing the lines. Due to that this product has been a time saver and improves staff compliance. They also state that it smells nice and feels it cleans better. “

Exemplary Corporate Conduct  ~ Bruce Oren, New Haven, CT

“This is the way corporations should behave.  After buying a used dental air compressor from a contractor who was clearing out an abandoned dental practice in Manhattan, I was dismayed to find a container with mercury amalgam in the box with the compressor. Rather than send this hazardous waste to a landfill, I contacted the company that made the mercury amalgam separator — Solmetex of Northborough, MA. Solmetex sent me a prepaid shipping container with detailed packing instructions so that I could safely send the mercury amalgam container to them, and at their own considerable expense have the hazardous waste safely disposed.

This is the kind of civic responsibility exhibited by all too few corporations. Solmetex should be rightly proud for having stepped up when they didn’t have to. They deserve special recognition.”
