“People have complained about this thing falling off on the first ride, I think maybe that’s a skill issue. If you follow the instructions carefully it secures itself pretty well, have had no issues there, also the shape can be slightly trimmed on the sides with heavy duty scissors if it doesn’t fit perfectly under certain seats with narrow spaces (however that’s not recommended by manufacturer) also yeah it stops more than enough unwanted spray off the back wheel.”
“Instalation is ok, the plastic origami is a little confusing but the website video helps, and it worked well while it lasted but then it fell off on its second voyage. Kinda just wish they added a zip tie to secure it. My ass was not saved.”
“Put it on my MTB as instructions suggested, even watched online instructions. Went out with it on my first ride on track and road ride, didn’t come back with it. Came loose somewhere along the way. Less than ideal for MTB probably excellent for road bikes”
