I quite like the benefits of the design, having both increased ground clearance and lowered center of gravity are admirable qualities. The designers website is fairly good in detailing the benefits of these pedals, except in one regard:

On the website there is a solid claim of increased durability without any evidence backing up this claim from what I can see.

I think that in this regard, the pedals have two design challenges in regards to durability:

The bearing assembly is at the base of the pedal, with the bearings placed extremely close together. Wise of the designer to use heavier bearings in this case.

Having such a thin pedal, they have been made tapered up at the base with a thicker material, but most of the pedal is a fairly thin, non-reinforced material. That could potentially be trouble for a heavier rider who comes down from drops with his / her feet further out on the pedal, over time.

They seem to be strong enough, as they're pictured in use in some pretty heavy duty conditions. But the designer doesn't have any explanation or evidence supporting their claim to durability. I'd be worried about them in use over time personally, and it would be nice to see some information in that regard.
Just a couple comments:

- the bearings are massive compared to typical pedal bearings
- these pedals have been used for 1 or 2 seasons of pro DH racing
- they've also been used by a 200lbs+ rider on nearly a daily basis for some pretty tough riding

As an engineer I have no issues with the design of these pedals...I wouldn't be worried about durability or how they function. It's a great design. The only issues I have are related to needing customized cranks and the associated cost of having to buy new pedals and cranks. If Dean can sort out that element of the design and maintain the rest of the pedal's functionality he'll sell them quite well.
