Safe Skies 3 Dial Aero TSA Recognized Lock review

The Safe Skies 3 Dial Aero TSA Recognized Lock matches the Master Lock 4688D on price at $9.99 and stands out for two published details: it weighs 1.22 oz (35 g), the lowest weight any brand lists here, and Safe Skies promises to replace it free of charge if TSA clips or damages it in transit. The lock measures 2.25 x 1.25 x 0.5 in, uses a 4 mm shackle and a resettable three dial combination with jumbo dials that Safe Skies says are easy to see and operate. It comes in nine colors, and a set of 2 costs $17.99. Safe Skies lists recognition by the US TSA plus security agencies in Canada, the UK, Switzerland, Australia and other countries. On the other side, three dials give fewer combinations than Master Lock's four-dial models, and the store does not publish the shackle length, so check fit against your zipper pulls. We compared documented features and published prices and did not test the lock.
