This is great. You don't even open the bag. Just drop the bag on the stand, slide the lock, and that's it. It took me about 15 minutes to do decent size lot. I love how simple this system is. They also included two adjustable hooks that you lock the top of the bag onto so it has no chance of falling over if it's somehow tipped over too far. I did my entire front and back lawn and very happy about it.
