Easy to fit
Doesn't fit 20" Racing Boy
Used for 1 week or less
Although recommended in store, it is not compatible with 20" Racing Boy 500 - it would need an extra hole, different screws and adaptors.
The instructions is a joke, the parts on the pictures are different from the actual content of the package.
proper size
poor instructions, doesn't fit my bike
Response of the brand
Dear Sir,
I'm sorry to read that there has been a compatibility issue with this product.
I have just this very minute contacted the product manager at b'Twin to find out why this is the case as it should fit with ease.  He has sent me photos and the mudguard should fit perfectly.  There may be a fault with the bracket we supplied.  He is going to review the instructions.
Please accept my apology for the trouble this has caused.

Very average product for the cost

Very average product for the cost. I purchased cycle in past from Decathlon and the quality of the accessories was very good. But this time the cost increased and quality decreased.

The mud lands on your back.
Used for 1 week or less
This is a completely useless product. I got it installed properly by the staff when I bought my bike. The first time I went biking on the wet road I got mud all over my backpack, t-shirt, neck and hair. The plastic is simply not cover the wheel enough to protect you from the mud.
Had to take it back, but Decathlon guys are nice, I got my money back easily.

Low quality product
Used for 2 to 8 weeks
The plastic/fibre used in this product is very thin and it bent within 2-3 days. Now it keeps rubbing against the tyre. I think the quality/design needs to be improved.
