If you, as I do, spend a lot of time carrying plastic grocery bags between the store and the car and the car and the house, then this is a must-have item.  I purchased these handles almost two-years ago, and they're still going strong on almost daily use.  You can carry an amazing amount of weight with them, as the thick handle makes it much easier to grip.  Even if I'm carrying a light bag, I still use the handle because it prevents the plastic from cutting into my skin.  I stick a couple of these in my coat or pants pocket when I get to the store, then quickly thread them through the bag handles when I go through the check-out line.  This simple product has greatly eased the chore of going to the grocery store, and I commend this company for successfully bringing to market a product as innovative and helpful as this one.
