I have a set. Bought them several years ago prior to my acquisition of a set of OEM SRT luggage.
the image from the seller shows them neatly left to right. That configuration only works if
1) You keep the Roadster trunk divider up (don’t fold down the top)
or
2) You only fill them half way and pull the divider down over them
or
3) You use another “flat bag” under the divider and use 2 of these bags the the area that’s left

Don’t force the divider because it’s super easy to brake the trunk divider bracket

2 of the 3 bags separated at a side seam after 2-3 weeks of use
This was only my experience. I’m sure that others have a completely different take.

not sure how much they’re selling for now but if they’re inexpensive or on clear out it might be work getting
