Query: Simple & clean

Dropped one and broke it, but I've been more careful with the replacement and have had no further durability issues.The button-less operation is easy, and the display is very readable.In about 600 miles I've had only two or three erroneous spikes in speed pop up (67mph, etc.). Doesn't bother me, but may be worth noting for those with greater concern for performance and accuracy.
