Fenders with significant weaknesses

I bought the 28 "version of these fenders me 11 months ago (not Amazon). Although no attachment bolts were there, but I could see the old use. Now, after almost a year (I have to say I drive a lot and every time Weather - but for mudguards're here) Here are my experiences:

+ The installation went smoothly.
+ The struts are made of stainless steel.
+ The contact strips in the rear fender are fundamentally practical.
+ Connection clips for are.
- The front fender rattles with poor track violently back and forth.
- The contact strips were after 10 months both broken (no longer in contact).
- The rear fender is too short - dirt splashes on taillight and porter.

I would say for occasional cyclists who drive mainly in fine weather, the parts are already ok. For my needs, they are apparently not suitable, so I would not buy it again.
