I purchased the second one of this machine from Vevor. I also purchased upgraded one of these before. It is good when it works. I havent had issues with first two. I recently ordered another one, item arrived fine. After assembling it (i did it before), it has electrical issue and air circulation problem. I used it with the same exact setup i used the previous vevor machine. It didn't work. I wrote to customer service, it took them a while to respond. I am operating a business, last thing i need is a non working machine to take space in the booth. I put it in the box, thinking that they would take care of the issue. NOPE. They are dragging feet, everything they can do to avoid return. Asking for a video, this and that. All i am asking is for a replacement unit, not a refund or anything. This one is ready to ship back to them, they can run any tests, take as much videos as they want with it.
Anyways, its been over a week, back and forth. Nothing yet. They are still asking for a video. I need to go set up the non working machine, take a video and then pack it back together again. It is ridiculous.
So beware, do not feel confident that you will return if it doesn't work. It looks like this company is not backing up their product or quality.
