Yamaha DTXpress/DTXplorer/DTXtreme

Has anyone used their DTXpress outside extensively?  Just curious how 
it fairs outdoors (in the heat, sun, wind, snow...)

I played mine for a week in 90 - 100 degree temp last summer. I was the only one breaking a sweat! I was worried about dust but that didn't seem to be a big problem ... at least it didn't affect the sound or they way the pads played.
