Sturdy. Professional. Butcher Block is a gorgeous wood, nice and thick.  Every part of this workstation is great quality.I use it daily for many hours and enjoy every second of it.  The little bit of time it takes to easily assemble is quickly forgotten once its ready to go.  Great size, wheels and brakes are sturdy and work great.  Great drawer space. More storage underneath than how it appears.  Speed rack excellent bonus.  And the cutout in the board makes for extremely easily removal of waste.  Love this piece and would highly recommend.
