I didn't send back my heater that was used. And if the uv works, she may keep. Or she may not
The recommend came from having the option to return if it doesn't work, within the stated timeframes and that's fully legal.
Some people send back a uv, some keep, hopefully you are taking close inventory of the process to help someone along the way but she can access a uv quite easily exactly as stated. It's ideal if you were that resourceful about fixing up this tank invasion, the links and all. The passion.
The option to return and exercising that is not against policy. I own and don't plan on returning someone's rental neotherm as we speak. Y'all got a bit hyped IMO, par for web poster diversity is ok
