No-Load/One-Wheel Syndrome
A common misconception is that a Torsen-Style Differential is useless under a no-load situation (e.g One wheel in the air). Although true to an extent, this no-load situation does not apply to the modern day car with Traction Control (or eDiff). For those without traction control, there is a very commonly used solution to the problem (used by professional race car drivers over the past 30+ years) that our competitors will not tell you; simply left-foot brake

For the Back Pocket Carrier out there....
Material Type: Leather, Color: Forest Brown-4337
I think this wallet is awesome! I've been carrying for about a week and it is working out great. I usually don't carry cash but for the last week, I've actually had a little cash on me. Instead of using the clip on the back (that clip is pretty tight and I don't like the look of having cash there), I just put is under the ID flap and the magnetic closure holds it in place. I love the color, the trigger works great, and the cards are held securely even when it isn't completely full. I also like the size. It requires me to carry less, which is something I need. (I realized two weeks ago that I had been carrying an old debit card in my old wallet around that had expired in 2023 and it turned out that I didn't have an account at that bank! hahahahahaha. I must be getting old.). This is important to me: I carry a wallet in my back pocket. I always have and that is what is comfortable to me. Front pocket carry feels weird to me. I've been carrying this wallet in my back pocket and sitting on it with no issues. I'm a big guy (300 lbs) and, so far, it's held up great. In all honesty, I do take it out of my pocket and put it in my console when I drive, but that's it. Everywhere else I go, and sit, it stays in my back pocket. I know it's only been a week, but I'm glad to see that I haven't crushed it, or deformed it, or anything. Ultimately, it's been great and I'm glad I got this one.

Best Wallet I’ve Owned – BULLIANT Magnetic Metal Wallet Is a Winner After a Few Months
Material Type: Leather, Color: Tiger Eye-4339
I’ve been carrying the BULLIANT Men’s Magnetic Metal Wallet every day for a few months now, and it’s easily the best wallet I’ve ever owned. It combines a sturdy metal frame with a full-grain leather flip cover and a strong magnetic closure that keeps everything secure and tidy. The RFID blocking works great, and the overall build feels premium without the crazy price tag of some big-name minimalist wallets. What I love most is the functionality and everyday practicality. It holds my cards securely, the magnetic flip makes accessing them quick and easy, and the design keeps things organized without too much bulk. Cash storage is straightforward, and it just feels solid in the pocket. After a few months of daily use, it still looks and works like new—no loose parts or wear that bothers me. If you’re chasing the absolute slimmest possible profile, this might not be the one for you — it’s not quite as ultra-thin as a Ridge wallet. But for me, that extra bit of comfort and capacity makes it perfect. It strikes a great balance between minimalist design and real-world usability. I don’t feel like I’m sacrificing too much slimness, and the added features (like the magnetic closure and leather accents) make it more enjoyable to use day-to-day. If you want a durable, well-designed metal wallet that feels high-quality and performs better than cheaper alternatives, this BULLIANT model is absolutely worth it. Highly recommend!

Feel secure with your cards and money!
Material Type: Carbon Fiber Leather, Color: Black-3926
This is a cool wallet. My previous wallet didn't protect my cards and as a result they would get damaged. This wallet is like bullet proof and fits all of my id and credit cards perfectly. I really like the magnetic fold which is very secure, but the most comforting thing about this design is that my cards cannot be scanned. Very secure. Highly recommend Bulliant wallets!
