Job/Oddysea is junk. It is really garbage and should be illegal to import.
There are thousands of stories of Jebo equipment starting fires so they changed the name to Oddysea. There is a much better dealer out of California that sells MH on Ebay and online. They build them themselves for a great price and use quality parts. I think it's called AquaCave.
Ask me anything about Jebo Oddysea and I can give you honest answers. A friend of mine is a wholesaler for the crapola and has been sued several times because of failed merchandise. As he says, the profit is to good to stop selling it. None of it is UL listed. If a website says it is, they are lying. I know for a fact that the equipment does not come with instructions or any certifications. Retailers can buy stickers from China that look like UL tags and also print their own instructions if any are given.
