arguably better than most that i have used
this is the only mop i know of that holds a good amount of water and doesnt drip it everywhere. holds a good deal of water for outside when you dont want to have to go to your bucket after 2 panes of glass (heat will obviously change that). and when inside it will do a good job of not dripping water on your customers floors. as long as you do not use them on post construction windows and you rinse them out after the day is done they will last for a while without getting smelly. they do break in after about a month but you can use them for a while longer.
