I think that there is no problem to use, but I think that I would like to be produced a little more stubbornly. I think that it is convenient that there is storage to put the pump after use. Although the pump which I used up to now was a single battery, this time I thought about the AA battery, but it can be used normally.
I used a pump with a single battery specification but it was broken so I bought it as an alternative. The impression of using it is late due to AA battery specification. Also, since the main body is shorter than the poly tank, refueling can not be done to the end. The bargain pump of 980 yen for the home center is better.
