I've seen, handled, battery powered inflators before and thought how cheap they are, and never bought one. But eventually I wanted to buy something for current 'toys'.
So I bought this one. I unpacked it, and felt the plastic, toggled the switch, and judged the air volume blowing and sucking. My conclusion - this is the best I've touched so far. The rocker switch is nice, not a cheap switch often seen. A note about plastics from my experiences. I can immediately judge plastics when I handle them. Good plastics have a smooth silky feel to them, cheap plastics just don't feel that way - hard to describe, but I know it when I feel it.
Not too much more to say about an inflator, and nothing to say negative. I believe I made a right choice with this unit.
Thus, I recommend this inflator. So far I haven't run down the first set of 4 ea - D batteries and can't say how long it will run on those, but will know soon with this continuing good weather!
