One of the advantages the touchscreen on our Microsoft Surface or other Windows 8 device is the artist uses it presents. You can basically turn your Windows 8 touchscreen into an art canvass.
The Sensu Brush is a tool that can help you draw with not only a stylus point but also mimic brush strokes. It's not your run of the mill Windows 8 accessory but it can come in handy if you like dabbling with art/sketch apps.
The Sensu Brush is a two piece brush that is about 4.5" long when capped and weighs about as much as regular paint brush. The body of the brush has the stylus tip on one end a comfort grip in the center and a brush on the other end. The cap can be placed over the stylus to give the brush a more traditional feel to it.
While my artist skills are rather lacking, the touchscreen on my Acer laptop, Surface RT and Windows Phone was very responsive to the stylus and brush. In using the Sensu Brush with Windows 8 RT apps such as Draw and InspirARTion you can feel a difference in using the brush as opposed to your fingertip. You do have to apply a little pressure when you're using the stylus to avoid skips in line draws.
The quality of build with the Sensu Brush feels as it will hold up to use but you do have to be careful in placing the cap over the brush for storage. If you aren't careful, you can bend the bristles. Then only real nit with construction is that the rubber comfort grip is a dust magnet.
All totaled, the Sensu Brush is a nice accessory for the artist and their Windows 8 device. The brush is currently running $39.99 and you can find it here at Amazon.com or directly from Sensu's website.
