## Customer Reviews

### ⭐⭐⭐⭐⭐ Duh, check function of any purchases
*by M***M on February 27, 2025*

Worked perfectly as soon as I opened the perfect box it came in with no damage. The beefy still is definitely a plus. I bought a $20 quick lock at a store here in these parts called Bi-Mart. It was puny compared to this. I had the red bar and gray base. First thing I did was check the lock and key functioning. Smooth as a bottom dollar. Looks great works great. Unless you are going hardcore all locks are just to keep honest people honest. I would suggest if you're serious about stopping or making it harder for your rig to stay yours is wrap some New York bicycle antique theft chain through your leaf springs through the tires rims with an American Lock on the inside of everything so it's hard to access with a cutter. Because you're not going to use bolt cutters on those chains. They are specifically shaped so that bolt cutters cannot cut through them and they have a sleeve made of cloth that definitely stops bolt cutters either way that's not going to work. They'll have to start carrying apart leaf springs axles and the tire with the rims etc. You got to make it harder than the next guy. I doubt your rig will be worth the time because it's easier to take the next guys. And don't show your neighbors what you have or how you do it to keep it safe. Use cameras, it's 2025. The more you put on remote solar lights and everything else you can do if you really look into it. This applies to all personal property. Either make it hard enough to they go to the next Target or if they take it it's destroyed and it's useless to them. Always watch your surroundings and actually look around yourself because you have to be the watcher because no one else is going to be watching out for you. And if they do you never know who they know and what information they have for the people wanting your property. People use anti-theft bars on their steering wheel. You can bend the steering wheel or cut right through it removing that and teeth theft bar. Here on Amazon you can buy a $20 pedal lock stainless steel and they're not going to take the time to cut through that. I put three of those on my rig. Along with a lot of other things. All rigs are easy to steal. The be creative watch YouTube and see how they break stuff and think outside the box. Look up New York Kryptonite KryptoLok Series chains and locks. Research d style locks. Put a couple of these heavy duty chains and locks through your tires leaf springs axles etc. Good luck on stealing that without being seen or heard. Or moving it while we're moving the tires and cutting through chains that are definitely going to attract attention. But this lock was awesome I like it super bulky not weak looking. You have to send a message by the things you put on your rigs and property. You're not going to get this easy and it's going to cause you time and you're probably going to get noticed and caught. Because you can't count on the police to protect your property or find it. Put some air trackers on it. Basically invest as much as you want to if it means that much to you. I can't see anybody taking off for those chains and locks on every tire wrapped around every axle I leave spring. And that's just for starters. Solo-powered lights work great because they have the capability of weather resistance functionality and battery charge. Cameras are easy to use. Duh, always test out anything you buy immediately or before you purchase if possible. That is the owner and purchaser problem if they don't. Those are the people that are the ones that will be the target instead of you. Because it's easier to steal from someone who doesn't know what the heck they're doing. It's 2025 wake up
