The Good: Solid construction, decent support, better looking (and simple style) than most other 'casual' SPD shoes, waffle sole gives plenty of grip. Like the extra velcro strap.
The Bad: Can be a bit heavy compared to other shoes (Shimano's DX shoe comes to mind). No lace protection. No ankle protection.
I've used this shoe for DH racing and XC riding for close to two years and have been very satisfied. The Warner is a fairly straight forward shoe with no problems at all. I've even brought these shoes to the bike park by accident instead of my 510s and did fine with them on flat pedals (just remove the SPD cleats) as the waffle soles provide great grip (not the insane grip of the 510 Stealth Rubber but the difference is negligible). Fashion-wise, these shoes are great with a pair of jeans or some MX gear, which really doesn't matter much but I know there are folks out there who are fashion-conscious in this sport.
