Query: Can't get the most important thing right

This isn't a complicated product. Put the glass tube into the holder and wait for it to rain. Pull the tube out when you want to know how much it rained. Look at the water inside, match it up to the lines and numbers painted on the outside of the tube, and voila, you have your answer. But wait, you don't have your answer, because the lines and numbers that you're looking for have worn off. After just a few weeks of use. In mild California weather.To their credit the manufacturer has agreed to replace the tube, sight unseen, but that only tells me that they are aware there is a problem. A little quality control and product testing would have avoided the hassle for me and them. For that reason I suggest you look elsewhere.
