These Victorinox TSA combination luggage locks work, for me, as advertised. The locks, while not necessarily small, are a good size, weight and substance. The construction seems very good, and having taken these on some trips successfully, with no incidents, I am pleased with their performance. With these locks on my luggage I feel that added security while traveling. The red pop-up indicator works, letting me know in advance that TSA personnel have inspected my bag. The combination changing is easy, pretty much the same as other brands that I own/have owned in the past, with no issues at all. Lastly, I do like the design, but, hey, it's only a luggage lock and mostly out of sight, especially when flying. As long as these are not clipped from my bag, I believe they will last a very long time. Highly recommended.
