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

Perfect Mini Backpack for almost any occasion! Fits 11 inch ipad
Color: Black, Color: Black
Giving 5 🌟🌟 🌟🌟🌟, even if I havent used it yet! because it: -arrived in perfect good packaging, protected and nothing missing. -11 inch ipad fit with its own pocket(although it did reach the very top of the bag and can feel its corners) - can fit 2 regular plastic bottled water on both sides - coin pocket(tho I'll be putting coffee candies and mint instead) - spacious enough for mini snacks or notebook/light books. - has 2 pockets inside - 3 pockets outside(1 at back, 2 at front) Good value for money. Good for travels!(be using for camping). And I think its water resistant. It is a simple, cute, very functional bag for many occasions Wish: that the strap would be a bit longer, although I did have extra 2.5 inches before it rested comfortably at my lower back.

Great Medium-Sized Backpack !
Color: Khaki
This is the best medium sized backpack ! Bought it mainly for that it fit my Kindle since a smaller backpack didn't and the multiple compartments (more than I need but easy access). Lightweight, water resistant, great value and the quality so far is great. I especially like the locking feature should I need it. It's much lighter than my travel purse (PacSafe that I would still use for travel, especially international.) The "security" feature is an added compartment for more local travel.

Great bag, short shoulder straps
Color: Black
Love the size and the many, many pockets. The quality is great, it's really well made. But the shoulder straps are short. Like for a little kids backpack short. I love the bag so much I'm getting a kit to extend the should straps. But yeah 5 stars for the bag, minus 2 for the short shoulder straps.

Great mini backpack
Color: Black
I love this backpack purse! It has so many pockets; 2 side pockets great for water bottles, umbrella, or my sunglass case. And I love the safety features. The only reason I gave it 4 stars instead of 5 is that the adjustable straps sometimes slip out. I will need to bring it to the shoe repair shop to have one more fold sewn into the end of the strap to prevent it from continuing to slip out.
