The smartly packaged mask was intuitive to use, and didn't feel much heavier than a normal mask. A yellow button on the upper right side of the mask snaps pictures and starts or stops video. A second red button, raised at a different level, serves as a power switch and toggles between video and camera mode. A red light, visible underwater in picture mode, switches off briefly when a photo is taken, until the camera is ready for the next shot. In video mode, a blue light shines when on standby, and blinks when the camera is rolling, to ensure you don't waste battery and disk space. A standard USB port allows quick transfer, and an expandable microSD slot lets you upgrade from the 16MB internal memory that holds 27 to 35 photos, or 40 to 50 seconds of video. Two AA lithium batteries are included. Liquid Image claims they'll last for 400 pictures or 30 minutes of video, but the kids got a bit tired before I could fully test that claim. Standard AAs work just fine as well. The camera smartly turns off after two minutes of inactivity. It even includes a storage compartment for lip balm, cash, or two extra batteries. The mask comes packaged in an adequate plastic box, and some photo editing software is included that's unnecessary and never reached my CD drive.
