Query: Trash after eight months

When I purchased the lock I liked that is a good size, got good reviews from people who test locks, and seemed to be good value for money. I bike to work five days a week.I used the lock regularly for eight months until today, when I dropped the lock part without the shackle attached. This was the first time I had dropped it. The plastic cover of the lock broke into pieces and flew off in all directions. The key would no longer turn to close the lock with the shackle in place.Lock went into the nearest trash can and I hope to find a different brand that can make a quality product.
