Twice they sent me something different. What the company is advertising has a hammock, and an 11 inch wheel, what they sent is different, and they did this twice. The second time after I confirmed with them that they actually have the item they are advertising for. Returning these things is not easy or convenient for me, and I needed something for my pets, so I opted not to return them a second time, but the company should stop advertising a product they don't actually have. It's not cool to put customers through the hassle, and the cost of having to return stuff.
