LARQ Bottle PureVis 17 oz

A family member ordered one, it worked fine for about a month on the initial charge. One day, while initiating a normal cleaning cycle with the cap on the bottle, the light ring turned orange. I initially thought it was low on battery, so I charge it. It turned solid green relatively quickly, indicating a full charge. We attempted to use it again, and it worked fine. However, when attempting to use it again later the same day, the cap turned orange again. Without reading the manual, I thought it was indicating low battery again, so I plugged it in. It turned solid green after only a few minutes. I couldn't get it to work again, it was always the orange light, so we returned that one to Amazon and order a new one. This one was shipped directly from LARQ, costs $9.95 in shipping. I just received the new unit today, after reading the manual again, I realized the orange light meant the ambient light sensor thinks the cap is activated outside of the bottle, not a low charge. So the light sensor malfunctioned in a month. The new unit also has a tiny chip on the bottle. The product is based on a good idea, but it is manufactured in China, so quality is questionable. I just hope the new one will last more than a month. In hindsight, maybe I should not have ordered it again. I cannot fully recommend this product, based on it's questionable reliability and quality, expensive price, and it's made in China. Update: The bottle cap is not water tight. If you put ice cold water in the bottle, you can see condensation and water inside the bottle cap. This happened to 2 bottle caps. When this happens, the cleaning cycle will not activate, you get the orange light. I contacted LARQ support about this, they haven't responded in 7 days. Either I have bad luck or the bottle cap has a design flaw.
