Great gym locker lock.
5 Stars
Great gym locker lock.
I needed a lock to secure a locker in my local YMCA. This very simple lock does exactly that. Do I expect it to hold up to bolt cutters or serious manipulation? No. But that is exactly what I expect from a simple, cheap, straight forward lock. It is enough to secure my belongings in a locker room--that is all I was looking for.The lock comes with a key object that allows you to set the combo for the lock. I like how simple it all is. Also when it comes to opening the lock it is a lot more straight forward to open than the turning locks. It is easy-to-use for day-to-day gym activities.Dimensions can be seen in the photos I have uploaded.Pros:*Secure enough to protect a locker in a locker room*Easy to use*Quick to useCons:*NoneAdditional Considerations:If you are looking to secure something more valuable that is not in a high traffic area like a locker room--thus being exposed to more manipulation or bolt cutters--this is not the lock you want. This lock is very simple and used purely to secure stuff in a locker room setting where you will not have someone coming in with bolt cutters getting into your stuff. If you need something more secure, look elsewhere.Overall: 5/5 stars (&#62;=.5 rounds up, &#60;.5 rounds down) =&#62; 5 starsIf you have any further questions regarding the product in my review please leave a comment below and I will get back to you as soon as possible.

Reviewed in Mexico on March 19, 2024
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.
