Cart Car seat Holder

Has anybody actually used this before?? Thoughts if you have?? I did read the reviews, just looking for feedback here as well. I figured I’d get more responses in this group rather than the product recommendations one

Edit: Only answer if you’ve used please or know someone who has. That’s all I asked for. I don’t need y’all to say anything else. If you don’t actually look up the product and know about it don’t make assumptions on how it works. Thanks
