A rating of one star given because it was a strap and it did have a lock, but it is as much use as a chocolate teapot. The strap could be easily removed without touching the lock and in fact the strap could not be tightened enough to be of any use at all. The advertising bumf was very good and I fell for it hook line and sinker - It stated that special keys held at airports would allow customs access without damage and an indicator on the lock would inform you that access had been made using this key. This was what convinced me that the strap was designed to be a functioning security device, a further examination of the sales wording identified that 'Security' was never mentioned. I felt that the product was poorly designed and that I had been misled by the product description and I sent an e-mail to the supplier asking for their comments, as of yet I have had no reply.
I have bought many things through Amazon and this is the first time that I have bought rubbish and the first time I have not had a reply to an e-mail sent to the supplier.
