The Good: Light. Bomb Proof. Great "under foot" feel - stable, big, "connected". Easy pin replacement. Great pin pattern and traction.
The Bad: Pricey - but you get what you pay for.
Overall Review: Awesome. Worth the buy, my personal top preference for flat pedals. If you have problems with ripping out pins and clipping rocks, these will take the abuse and keep your feet in place at the same time. Also great if you just want your feet to stay planted and apply power without hesitation. Spot on design and construction.
