for the whole family 2

Model used by the whole family, children can use water without a problem and adults have fresh water (1/2 liter) almost all the time. small fan noise when the level of fresh water decreases, but frankly not a problem (when talking we did not even hear ...). Attention only has the quality of the bottles that you buy because if the plastic is thin bottle will struggle was empty, the personal "Luchon" are very well ..... very happy with my purchase.
