I just got this lock few days ago but I haven't used it yet. I have two main problems with it:
1) It's large and heavy. The lock that I use now is almost half the size of this one! It might be this big because it has the TSA lock with the dial...but for me travelling outside the USA, this is not so practical. So I might just use it when I go to the US.
2) It doesn't look very steardy. The dials are not very secure and move sideways. You that they would just break or fall apart.
