I purchased this and within a week it stopped working. To try to get a refund was a mission. They wanted a video of the product not working. Once it was sent they wanted another video of us dismantling it to show them the control area. When I gave a dislike on the service I was told my the person helping me out to remove my dislike and questioned why I gave it. This person kept asking me to remove it and would not send me the necessary link I needed. He sent me the link until I took off the dislike. Not only that but instead of giving you your entire refund from the start they take days to reply and keep asking you to keep the item and if you want $20, and then I would say no I want my full refund and then 1 day or 2 later they reply with keep it and $40 refund. It was a whole mission to try to get my money back. Think twice when purchasing.
