Review: Does what it says on the tin. - This is the third MuckyNutz mudguard I've bought (see my other reviews) - all are very lightweight and pliable and unlikely to break. This is the easiest to fit because it just clips into the seat rails, although it's easier said than done. I added a tie wrap in case it gets dislodged and goes flying without my noticing. Because it slants down towards the back it doesn't get in my way when sliding back over the wheel for manuals, drops etc, and it doesn't interfere with my drop post. It seems to stop most, if not all, of the spray from the seat upwards, though I haven't given it much of a stress test yet. It weighs next to nothing and is very reflective, as you can see, though I can't see much of a use case for that. Doesn't look as cool as the other MuckyNutz mudguards, but I prefer practicality over cool any day!
Review: Good Fender - I recently purchased this small mud fender for my bicycle and have been generally satisfied with its performance. The mud guard is easy to install and fits securely on the back wheel of my bike, effectively blocking mud and debris from being flung onto my back and backside while riding. One of the things I like most about this mud guard is its compact size. It is small enough to be unobtrusive, yet large enough to provide effective coverage for the back wheel of my bike. It also has a sleek, low-profile design that doesn't add any unnecessary bulk or weight to my bike. In terms of durability, the mud guard has held up well after several rides through muddy and rocky terrain. It shows no signs of wear and tear, and I expect it to last for many rides to come. Overall, I am satisfied with my purchase of the small mud guard. It does a great job of keeping me clean and dry while riding, and I would recommend it to other riders who are looking for an effective and affordable mud guard for their bikes.

### ⭐⭐⭐⭐⭐ Does the job
*by C***S on 7 January 2021*

Certainly reduces some of the muck on my shorts and an improvement in overall reduction of dirt on my back. I did not need much more than this and they are easy to fix and remove
