Overpriced and too small

After I installed the reflector yesterday, I can only say: What a mess! The reflector is ever too small. Maybe he's meant for a children's bike ... but this is not described.
By the way too thin cable ties and including at Legend rubber in conjunction with the completely inappropriate from Radius ago recess on 'holder' he is unstable on the frame. Once come with the brake lines on it he moves the same from his position. Sure, I have a mountain bike, but I thought nothing can by fixing with cable ties go wrong. In my MTB I had to concatenate both cable ties in a row. Maybe I'll try to grind the holder slightly and take a better cable ties.
Pricewise, the part is then also relatively overpriced, and the delivery went in absolute snail's pace. Next time better to the local bike shop.
