Is that the model with a velcro release strap on it?
In any case, all of those clip on plastic fenders are generally equal in their effectiveness. I would humbly suggest buying the cheapest one you can find or just make your own out of an old election sign or 2L pop bottle or what have you. There really won't be any significant improvement or differences in performance until you jump into full, eyelet-mount fenders (or the non-eyelet mounting equivalents, ie, honjos, raceblades, etc...). Planet Bike makes reasonably nice bike accessories at affordable prices and donates a portion of their profits to bike advocacy groups. Maybe check out what they have to offer?
