Amazon's system marked an item I returned a year ago as not received and charged me for this return, but the chat bot already knew they had received it.
I bought an electric start generator that stalled out after 20 minutes consistently, This unit can run all the essentials in my house whenever needed.
I called and told the rep it runs great but all of a sudden it dies for no apparent reason.
He gave me full credit for it and told me to keep it or donate it.
I figured out the next day that is was my basement dehumidifier trying to turn on and the generator could not handle it.
It was fine the entire time. It runs on propane or gas and has a clone of a Yamaha engine and is made by WEN.
It probably depends on your account. If they don't think you are trying to game their system and you are a deep pocket consumer, they probably won't put up too much of a fight, they'd rather keep you hooked.
Prior to saying it was propane I thought it had a lithium battery. I think those are hard to accept as refunds due to shipping regulations, but maybe it's similar.
