I just switched over to clipless pedals so I dont have a whole lot of background knowledge on the subject, but here is my take. These fall into the 'good not great' category. Having ridden on some shimano SPD and LOOK (something) pedals, they definitely come to play.
I prefer them to the SPDs due to the platform size, and I really couldnt tell the LOOKs apart from them. They are really easy to clip into and hold my foot great. Clipping out is also a breeze, and obvious when you are in or out, which is very nice to avoid the embarrassing stoplight bails. I also like the width positioning of the pedals - they feel like they're in the right place. I would recommend for the casual but interested road cyclist, but Im sure there are better options out there in terms of weight and strength.
Although I've only put a few hundred miles on them so far, there are a few things that I am hesitant about when it comes to these pedals. First of all, the pedals are made of a composite material. While I have not had any durability issues, I have a hunch that they will break or muck up a lot easier than other materials. Also, the shoe cleat has a huge hole for the front screw - so large that I had to use a washer to get a decent purchase on the cleat (but I didnt use the screws it came with - so that may not be an issue). Lastly, they have a lot of play when clicked in. This can be tightened/loosened accordingly, but even still there is more than what I would like (but I prefer not much at all, so may not be an issue for you).
Overall, good into-level cleat, I personally would recommend it for someone who is interested in cycling but not unitard suited people dropping 3Gs on a frame.
