So far so good
Although I haven't had a chance to use this product, it fit easily and seemlessly into the intended slot. It looks solid enough and appears durable.

Again with the zipper problem
The bag is okay. Don't have too big a problem with the size and all but one major problem is the lousy zipper. Read lots of problems about them and I had one too the first month or so. The other worked but now I have problems with that one as well. I cannot zipper it all the way or the one functioning zipper comes off so I have to keep it open slightly and get pelted with cut grass till the whole plugs up.

The other problem is that it does not hook on so well so if you lightly bump into something the bag falls off...not major but a pain in the neck.

Side bag
it is the normal sidebag for your clippings. Get it if you have a landscaped yard so you don't have to clean them up!

The mower is great, this is... not so great
It works. It's "ok". The design allows you to hold/carry/unzip the bag and empty it into a bin with ease. However,

1) It's sort of small.
2) The metal rod that is supposed to NOT turn is held in place by a small nub of plastic in the lawnmower body that immediately gets rounded out and starts turning freely (not a big deal)
3) Occasionally, when mowing on a curve, if nearly full, it detaches from the mower on its own. It might be nice to have a slightly better locking mechanism.

Meh. You gotta get one unless you have some other solution for the debris on your lawn. And if you do, let me know.

Just what I wanted.
The bag attaches simply and quickly. Holds enough for my small lawn. Double zippers are durable and open up wide to dump clippings.
