Features:
- EFM8BB21F16G MCU pipelined 8-bit C8051 core with 50MHz maximum operating frequency.
- A dedicated high-frequency driver makes the start more smooth. ESC maximum speed is 500k eRPM.
- BLHeli_S firmware is designed for superior performance in multirotors and uses hardware generated motor PWM for smooth throttle response and silent operation.
- Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active freewheeling.
- The code supports regular 1-2ms pulse width PWM input, as well as Oneshot and Multishot. The input signal is automatically detected by the ESC upon power up.
- Supports Dshot150, Dshot300, and Dshot600. Dshot is a digital signal, the anti-interference ability is stronger, and do not need throttle calibration.
- The silicone twisted-pair of the throttle signal cable increase the service life, and effectively reduces the crosstalk caused by signal transmission, and makes flight more stable.

Beautiful Wallet
Color: With NO Logo - Smooth Nappa Black
Well constructed and beautiful wallet. The black Nappa leather I ordered is soft and smooth to the touch and you can tell by the look, feel, and smell that it is high quality. I love that you can order this with both a logo and no logo for a clean look.
The design on this is well thought out.
I'd definitely recommend this wallet to anyone. It is an amazing value and far superior to any other $30 wallet I've ever seen.

Almost perfect!
Color: With Coin Pocket - Forest Brown
I purchased this wallet primarily for its generous number of conveniently located slots and its coin pocket. If you can't fit everything you want to EDC in this wallet, you need to think about getting a sling bag! Having returned the same model in Grizzily Brown due to a stitching defect and ordered this one in Forest Brown, I can see it is a richer, lighter shade and the finish seems smoother and more refined. Some of my cards were tight in previous wallet slots, but everything fits great in this one. Why the one star off? First, this wallet is about a quarter inch too large in all dimensions, especially thickness. While it doesn't protrude out the top of my back pocket, it is a challenge to close the button on some pants and it is also snug side-to-side, so removal involves some wiggling until pockets stretch and the wallet breaks in. The leather used in its construction is smooth but stiff at first, given that it is about twice as thick as most American or European wallet leather I've owned: think bullhide. The smell is also a little off, definitely natural cowhide but processed with whatever is used to tan leather in India rather than in the United States. Finally, this looks like something that belongs in a pair of jeans or casual pants, NOT pulled out of a suit at a Michelin star restaurant. The stitching, evenness of dye and lines are far from perfect, but what it lacks in looks it more than makes up for in every day function, character, and anticipated durability.

The Best Wallet
Color: Boulder Black - Napa Smooth Black
This is the second wallet I have purchased from Bull Guard. The first one is identical and I have used it for approximately one year. The first wallet has held up perfectly. I just decided to buy a second one because I am so happy with the first one and I decided to break up my cards into frequently used in the second, new wallet and less frequently used in the first and older wallet. The capacity of the wallet is excellent. It easily holds all my credit cards, drivers license, bills, insurance ID cards, and my global entry card. The material, workmanship, durability, and quality is also excellent. The wallet is all leather and breaks in perfectly. The size is also perfect fitting perfectly in my rear pocket. For the price, this is the best man's wallet I have ever had and I highly recommend it.

Solid Wallet
Color: Wild Buffalo Grey
I recently purchased the ULL GUARD Buffalo Leather Wallet, and I’m genuinely impressed with its quality and craftsmanship. The buffalo leather feels durable and premium—this is a wallet that looks like it’ll stand the test of time.
What I love about it:
- Thoughtful Billfold Design: The bill compartment includes a separator, which is perfect for organizing cash and checks separately. It’s a small detail that makes a big difference.
- Plenty of Storage: There are numerous credit card slots, making it easy to keep all your cards neatly arranged and accessible.
- Clear ID Pocket: The transparent ID slot is a convenient touch, especially for quick access to your driver’s license or work badge.
Overall, this wallet combines functionality with rugged style. If you're looking for something that’s both practical and built to last, the ULL GUARD Buffalo Leather Wallet is a solid choice.

A Quality Wallet
Color: Boulder Black - Napa Smooth Black
So far so good. The wallet has a great feel and is of high quality. It looks great and has plenty of credit card slots and I love the bill holder, with a divider. It is wider than I expected, but it stays thinner than the last minimalist wallet I had so the trade off is worth it to me. I would buy it again.
