I used this for about two seasons, from the year of purchase until May of this year. It works without any problems. There are no noticeable scratches or stains, but there is some limescale. The filter has been cleaned with citric acid. Please consider it as a bonus. I will send it set up, but let me know if you don't need it. I will wrap it in bubble wrap and send it in simple packaging. Please purchase only if you are not concerned about it being a used item stored by an individual. Shipping costs will apply, so please refrain from price negotiations.
