What We Love & What to Watch Out For
- Weighs just 35.7 grams — lighter than most smartphones, so you'll actually carry it everywhere
- Delivers genuine 4K UHD video and 12MP photos despite its tiny size and budget price
- Waterproof to 131 feet with housing — captures clear underwater footage during snorkeling or pool activities
- Simple setup gets you recording immediately — no complex menus or lengthy learning curve
- Limited manual controls restrict creative flexibility for users wanting precise exposure or focus adjustments
- Low-light footage lacks the clarity and detail of higher-end action cameras
- Battery drains faster during 4K recording — plan for shorter sessions or bring backup power
- Basic stabilization works for casual use but won't smooth out intense mountain biking or skateboarding footage
One of the lightest 4K action cameras available — especially valuable for travelers who'd otherwise skip recording due to gear weight.
