Works great, keeps the bike dry and fits perfectly. The reflective rim is damn bright when light hits the cover, so don't worry about your kid being parked at night. It also has two double snap nylon straps to keep the bag firmly under the bike although I never had to use them. Another nice feature is the small safety chain holes at the front and back of the suitcase, so you can use the hardened safety chain to protect your child with the suitcase. The bag is foldable and comes with a pouch so you can take it with you when you travel.
