Professional editors praise the iM30 for its unprecedented compactness, solid build, and surprisingly bright output (GN 15) that handles most direct-flash scenarios. They also value its retro styling and the inclusion of optical wireless S1/S2 modes, which bring remote capability to a pocket-size unit. The main criticisms focus on the fixed head and limited power, which constrain creative lighting and performance in bright conditions.
Everyday photographers love how the iM30 slips into pockets and adds just enough light for street, travel and small-studio work. Reviewers repeatedly mention its excellent price-to-performance ratio and practical brightness, while no major complaints appear in the available user data beyond the expected limitation of a non-tilting head.
Professional reviewers praise the SL01 for its unprecedented miniaturisation, high CRI and convenient USB-C charging, positioning it as a budget-friendly entry-level speedlite for beginners and travel shooters. However, they consistently note the lack of TTL, bounce capability and video lighting, which limits its appeal for more advanced or video-centric workflows.
Everyday users celebrate the flash's pocket-size portability, straightforward operation and reliable battery life, especially for social-media content creation. Recurring complaints centre on the manual-only nature, the relatively slow full-power recycle, and the absence of bounce or video-light functions that competitors provide.
