But e-bikes containing lithium-ion batteries are a newer challenge. "When a battery fails, it doesn't necessarily ignite, it will often produce some off-gases," says Stephen Welch, senior lecturer at the University of Edinburgh's Fire Research Centre. "Those off-gases are toxic and flammable. If they accumulate, you can have an explosion risk."

All that being said, there are some notable drawbacks. The Flip is relatively heavy and awkwardly sized, so you can’t slip it into a purse or easily carry it around. Prints also take up to 15 minutes to develop — during which they must be shielded from light — which can be quite an inconvenience. Low-light performance remains a weak spot as well, and I struggled to capture indoor shots given the contrast and saturation are lower than with Instax film. Admittedly, this gave my pictures a more dreamy, vintage look that felt artistic, and you can use the Polaroid Lab to slightly adjust the saturation and exposure settings.
