I purchased this grass catcher for use with the American Lawn Mower model 1705-16, for which this unit was labeled compatible for use.  I would recommend that anyone with the aforementioned model mower spend the $20 on a better lawn rake, or having the neighbor kid pick up grass clippings, or a down payment on a leaf blower, or on materials to build your own grass catcher attachment.  This attachment is absolutely useless for the 1705-16.  It does not fit well at all, so that a large portion of the grass slides out neatly piling as you go (which looks worse than if you do not use the attachment at all).  Not only that, this attachment has a capacity of approximately 6 toddler sized handfuls of grass.  Seriously, you can only mow 10 to 15 linear feet before the catcher will not hold anymore without dumping it out (due to the way the catcher fits on the mower), and that is on flat ground - it will not hold anything if the handle bouces up.  The catcher can be modified to work in an almost mediocre fashion if you want to put the time and materials into reworking it, but honestly you would be better off starting from scratch if you were doing this.  This catcher is very cheaply made junk (four coat hangers and some netting to be exact) and is not in any way durable.  I was quite disappointed by this, because the American LM 1705-16 mower I have is a very good little reel mower and a quality product.
