Query: Don't waste your time

I picked this cable lock up at the LBS Friday afternoon. I wanted something to secure my front wheel. After spending 5 minutes with the product, I don't trust it. I'm not a locksmith, but after having someone program a random combination, I can open it almost as quickly as I can if I were given the combination. There is about a 10 second difference. I'm not sure how other combination cable locks stack up, but I'm going to start looking for something with a key.
