This particular shopping cart was exactly what I needed for my sanity!  What I mean by that is....  I reside in a condo and shopping for groceries had become a super P.I.T.A.!!  I am in my 50s and I have been diagnosed with  chronic pain issues!  This cart has made my shopping experiences so much easier when it comes to hauling the bagsboxes etc.  It is larger that most carts and has a stronger bottom.  The insert is best idea ever!  It fits like a glove because it is made specifically for the cart.  On laundry days it is nice to look back and NOT  have a trail of socks, washcloths.... falling out of the cart!  The wheels swivel nicely and are super sturdy.  
I suppose I could have said that it is perfect for MY needs, so go buy one!  It is money well spent!!
