Review on Premium 3W Cargo Liner for BMW X5 2019-2021: All-Weather Custom Fit Trunk Mat - Heavy Duty & Black, Not for Hybrid by Will Anderson

works so we only keep it because I don't like the return. It's not flexible. I think a rubber material would work best. It is more of a hard plastic that is only slightly flexible. It doesn't fit perfectly. The perimeter has curves in some places for no good reason. My X5 is what it's designed for, but it doesn't seem designed for that particular trunk - it only works when you want it to. In general, I'm not entirely happy with the cost of the trunk liner. I just expected more for the money. However, it does have some clutter to keep the trunk from getting dirty, which is why I'm giving it 4 stars because it just doesn't impress. There's really nothing wrong with that.
