Highly recommend this purchase
I bought the Master Lock 142DCM for my gym locker, and it has been a fantastic purchase. The lock features a vibrant blue vinyl-covered aluminum body, which is lightweight yet feels sturdy. Because of the vinyl coating, I do not have to worry about it scratching my locker door or rusting if I happen to leave it outside in the rain. It comes with matching keys, and the mechanism turns smoothly every time without any jamming. Pros: - Lightweight aluminum body with a protective vinyl cover to prevent scratches. - Smooth key operation; no sticking or struggling to open. - Compact size makes it ideal for standard gym, school, or storage lockers. - Affordable price point for reliable security. Cons: - It is a smaller lock, so it is meant for low-risk security (like gym lockers) rather than heavy-duty outdoor security like storage sheds or gates. - The shackle clearance is a bit tight, so make sure to check your locker's latch thickness before buying. Overall, this is a reliable, budget-friendly lock that gets the job done with zero hassle. I would definitely recommend it to anyone needing a dependable small lock for school, the gym, or indoor storage.

Well made lock
Though it is an inexpensive lock, it seems to be well-made for its size. Where I have it in use is in the weather and doesn’t seem to affect it. I lock and unlock it often and works smoothly every time.

Great product
Simple lock, works great so far, no complaints! Seems sturdy, but I guess that will be tested over time. Glad it wasn’t very expensive either.

Light and secure
5.0 out of 5 stars Perfect little gym locker lock — super small, lightweight, and clips right onto my AirPods case! I grabbed this Master Lock Blue Vinyl-Covered Lock specifically for my gym bag routine before work, and it’s exactly what I needed. No more digging through my bag for a bulky lock or worrying about losing the key — this thing is tiny, feather-light, and makes securing my stuff effortless. Why it’s a game-changer for me: • Tiny & lightweight — Fits in the palm of my hand and weighs almost nothing. I clip the included key right onto my AirPods case with the built-in loop, so everything stays together in one easy spot. • Easy to use at the gym — Slides through the locker latch in seconds, snaps shut, and opens just as fast. The blue vinyl coating is smooth and quiet — no loud clanking like metal locks. • Secure & durable — Holds my wallet, phone, watch, and keys safely while I’m lifting or on the treadmill. The vinyl keeps it from scratching the locker or my bag. • Perfect pre-work hack — I throw my bag in the locker, clip the lock on, and I’m in the zone in under 30 seconds. No hassle, no stress. I’ve used it every morning for the past couple of weeks and it still looks brand new. If you hit the gym before work and want a no-fuss, ultra-portable lock that you can literally attach to your AirPods case, this Master Lock is perfect. Way better than the big clunky ones they sell at the front desk. Highly recommend — best $8–10 I’ve spent on gym gear in a long time!

Good quality product without being too expensive or complicated to use!
This item was purchased to keep an airtight box closed and keep people from opening it. I like that it is small enough for the box and it will last for a long time without any issues. I know that there are better locks on the market, but this one provides the same amount of security without being too fancy or too complicated to use. The material used in this lock will last for a long time and will serve its purpose for many years.

Smooth Action, Perfect Size
I needed a lock for darkroom and it needed to be a keyed lock but needed to be on the small side as some of the hasps are small. This is the perfect lock for that. It fits into the hasp and it's easy to unlock in the dark. The key is easy to locate on my keyring. When I'm done with that use, it's perfect for a gym locker. It's a Master so I know it's good quality and I'll be recommending it to my classmates.

Picked through this 30s after opening the package
Pulled it out of the post box, sat down in front of the TV, ripped the packaging open and in around 30s - 1m I had managed to get an open with my standard lock pick set. On a side note it is also so small and weak it could probably be pulled off whatever it is attached too. Could only advise use cases which require no security at all.

Nice alternative to a combination lock.
Easy to use! Nice to have the option for a key for those who have trouble seeing the numbers on a combination lock. Shipping was quick! Kept our locker, locked.
