This Review Title is Very happy with HydroBlast Pro!!! and the content is: Works great... just like the more expensive ones.  The person complaining about it not working was probably not putting the batteries in correctly.  It took me a few tries to figure out that there is a plus and minus mark (positive and negative) on the battery case top showing proper direction for battery placement!  Woo Hoo!  Love it!  Very handy!.There are other information for this review, one is This reviewer did not purchase it and the other is 1 people think this review is helpful.
