The pump plunger part of this warmer broke immediately. I called Vevor. They insisted that I send them a photo of the broken part. I explained that it was the internal part of the plunger that was broken and that you could not see or photograph it. I asked to return it. She refused to let me do this unless I provided a photograph of the broken part. You can see a revolving argument. The pump part was poorly crafted plastic. The other warmer pumps I have are all stainless steel and durable. I don't really like posting negative comments, but in this case buyer beware. I'm posting 5 stars instead of 1. I ended up throwing the unit in the trash. I have spent a lot of money with Vevor. You would think they would treat their returning customers better.
