I use them all the time although mine are just the plain store kind. I love them. They hold way more groceries than the plastic ones and stuff doesn't roll around and fall out of them. I love the longer handles as they allow me to put at least 2 or three on my shoulder when unloading plus the ones over my arms. It makes for quicker unloading especially because I have to walk up two flights of stairs to get to my house. A couple of mine are thermal lined and zip closed which is great for frozen things. I usually bike to the store with my cargo trailer and they make for easy loading and unloading into the trailer as well. The thermal ones kept ice cream frozen even in 90+ degree weather. I hate it when I forget them!
