I've been using fabric trolley covers for a long time (even before Covid became mainstream) and got tired of tossing the cover in the wash after each use. I used this product with my 2 year old at the grocery store yesterday and it was very convenient. It was easy to install and germ free for my child. After the products were loaded, I removed the biodegradable lid and threw it away, knowing I wouldn't have to wash anything when I got home. Thanks very much! I will buy again.
