Smart Wallet Ultralight Waters

before i got this, i was using a basic leather wallet that was heavy and got ruined in the rain once. after switching, it's definitely an improvement in weight and water resistance, but i'm skeptical about the tech features. they seem half-baked and not very intuitive. as a perfectionist, i want everything to work flawlessly, and this falls short. it's okay, but not worth the hype or cost for me right now.
- Pros: it's super convenient how light and small it is, fitting easily in any pocket without adding bulk. the materials feel very durable, like they can handle a lot of wear, and it keeps things dry even when it gets wet, which is a big plus for someone like me who's out and about a lot.
- Cons: the smart tech part seems a bit gimmicky—it doesn't always work smoothly, and accessing stuff isn't as easy as they claim. for the price, i expected more reliability, and it just doesn't feel like a huge upgrade from my old wallet in terms of functionality.
