Query: Fix it or don't sell it!

The idea is great...and it works well for about three times, and then quits.I bought my 3rd and last one. Following all instructions every time it still quit. I flush the unit after every use; hang it carefully so as not to damage the tubing; I do not store it with the batteries inside; I check the strength of my batteries.The company should look into the many problems, short lifespan, and fix the issues. I can not recommend this product.
