Okay, so I bought these straps thinking they'd just be 'meh' but WOW was I wrong. First off, they're THICK. Like, 'I-can-carry-my-kid's-scooter-without-feeling-like-I'm-about-to-snap' thick.
Used them to haul my daughter's Segway MAX G2 from school (yes, on my BACK like some kind of scooter sherpa). The padded shoulder part? Genius. Didn't even feel the weight after adjusting the straps properly.
Bonus: Came with an extra set which I immediately repurposed for my beach chair. Now I look like some kind of strap wizard at the park with all my gear neatly secured.
Only complaint? The buckles can be tricky if you overload them (learned that the hard way trying to carry what felt like a small motorcycle). Stick to reasonable weights and these are golden!
PS - If you have kids who constantly run out of battery on their scooters (why do they NEVER charge them?!), this is your solution. My son actually volunteers to carry his scooter now instead of whining about it.
