I frequent the gym 5 days a week and in doing so, you become more exposed to potential theft. Unfortunately, our gym discovered that someone was using bolt cutters to cut locks and steal belongings from customers whilst they worked out. All the lockers that were targeted had a cheap lock made out of inferior material and thin shackle, so I decided to purchase a superior lock just in-case I would become the next target. I have been using the Master Lock 178D for 3 days so far and I am very impressed with the quality of the lock. The material/durability is exception for the price you pay and programming the lock is a breeze - it took me 2 minutes. In addition, the shackle is thick enough to discourage a thief, as it would take a significant amount of effort to cut this lock. Overall, I am very satisfied with the security and experiencing using this lock and would highly recommend it. You can't go wrong for $20 and prime 2 day shipping!

This is a light and smallish look, with the shackle about 1-inch (thumb-tip to thumb-knuckle) across. A determined thief will kill it with a bolt cutter without too many problems, but as a casual deterrent it'll do a great job. The combination mechanism is in the bottom of the lock, with a small plastic "skirt" around it that will direct water away from the mechanism unless you install the lock the wrong way up! It's also quite neat in that it will only re-lock after you have scrambled the access code. If you try to close the lock with your desired combination still set, it'll refuse to lock. You can't click it closed but inadvertently leave it openable just with a pull. Setting or altering the combination involves a separate side key that is used to override the security mechanism - provided you have entered your existing code first. You will need to keep this side-key safe somewhere. Value for money, yes! We have other Master locks and they work well even after years in the elements. It's a bit bulky compared to a key lock, but seems solid enough.

Gutes und solides Schloss. Manko, man muss auf die Ausrichtung der Codes achten damit es beim öffnen keine Verwirrungen gibt :) Über Kopf ist es doch manchmal schwer :)

Necesitaba un candado confiable para el locker del gimnasio ya que los que uno compra en cualquier ferretería o supermercado a veces son fáciles de romper o abrir, en este caso ya había usado candados de la marca Master por lo que sé que son de calidad, este me gustó porque es de combinación así que no tengo que preocuparme por si pierdo la llave, además de que le puedes personalizar la combinación que tú quieras con una especie de llave que viene incluida, eso sí, es algo pesado y de grosor, pueden ver el tamaño con relación a una moneda de 5 pesos, pero por lo mismo se nota la calidad del metal, definitivamente satisfecho con la compra, y como tiene superficie plana al frente y por detrás le puedes poner algún sticker como lo hice yo para ubicarlo más fácilmente entre los casilleros del gimnasio. Lo compraría de nuevo y además me salió en oferta.
