this review title is: pretty good product and the content is: i like the larger capacity of the water tank i also like the rotating head and the good price the plastic has a strong smell that makes the water taste bad but you do not swallow the water so i doubt it is unhealthy also it is hard not to keep pushing the settings button while using the device because they are right where the grip is i think all the portable models might be like this.there are other information for this review, one is this reviewer did not purchase it and the other is 2 people think this review is helpful.
