My Buying Guides on Magnetic Stash Box Under Car
When I first started looking for a magnetic stash box to keep under my car, I realized there are quite a few things to consider to make the right purchase. Here’s what I learned and what helped me choose the perfect stash box for my needs.
Why I Needed a Magnetic Stash Box Under My Car
I wanted a discreet and secure place to store small valuables like my keys, emergency cash, and some tools. A magnetic stash box felt ideal because it’s hidden, easily accessible, and doesn’t require any modifications to my car.
Size and Capacity
One of the first things I checked was the size of the stash box. It needed to be compact enough to fit under my car without being obvious but also big enough to hold the items I wanted to store. I recommend measuring the items you plan to stash and comparing them to the box’s internal dimensions before buying.
Magnet Strength and Quality
The magnet is the most critical feature. I looked for a stash box with strong neodymium magnets because they stick firmly to the metal under my car, even on bumpy roads. I also made sure the magnets were well-encased to avoid scratching my car’s surface.
Durability and Weather Resistance
Since the box sits under the car, it has to endure dirt, water, and temperature changes. I chose a stash box made from heavy-duty, waterproof materials like thick plastic or metal with a rubber seal to keep my items dry and safe.
Ease of Access and Security
I wanted the box to be easy for me to access but not for others to find or open. Some stash boxes come with combination locks or screw-on lids, which adds an extra layer of security. I found that a screw-on lid with a tight seal worked best for me.
Shape and Design
The shape matters because it determines where you can attach it under your car. I preferred a slim, rectangular design that could stick flush against the chassis or frame. Some stash boxes are designed to look like car parts or are camouflaged to blend in better.
Installation Tips I Followed
I cleaned the area under my car thoroughly before attaching the stash box to ensure the magnet held well. I also checked periodically to make sure the box hadn’t shifted or gotten loose, especially after long drives or off-road trips.
Price and Warranty Considerations
Prices vary widely, so I set a budget but didn’t compromise on magnet strength or durability. Some brands offer warranties, which gave me confidence in my purchase.
Final Thoughts
Buying a magnetic stash box for under my car was about balancing size, strength, and durability. By focusing on these key features and considering my personal needs, I found a stash box that gives me peace of mind knowing my valuables are hidden yet accessible when I need them. I hope my experience helps you pick the right one!
