I bought this because I tried a compressed air can (exactly once) and discovered how it showered my UV filter with tiny water droplets, creating a much bigger problem. In short, this is the most powerful squeeze blower, but don't believe the hype that the force compares to compressed air-- it doesn't. Also, the blower is much bigger than the standard silver dollar-size, but it's still plenty small for a camcorder user to fit in their bag (for SLR users, maybe not).
