ZENSUI TEGARU II Cooler and Heater

This is a ZENSUI TEGARU II cooler/heater. It was purchased new from a store in June 2024 and used with saltwater for about a year and a half. I am selling it because I recently purchased a larger one. As it is a Peltier type, it may lack power in high summer outdoor temperatures, but I believe it can be used year-round indoors with air conditioning. This past summer, it stopped working several times due to overheating in an outdoor temperature environment. I am unsure if this was a normal reaction in high temperatures or a malfunction, so I am listing it as junk. Would anyone be able to make use of it?

Due to work, shipping will only be available on weekends. Thank you for your understanding.
