My wife didn't like the idea of the product from the pictures (she said it didn't look easy to use) but I'm a guy who drives a truck and I also have a similar bungee cord product I use to secure things in the bed of my truck (which I love). So for 9 bucks I decide to give it a try.
WOW!
Now we're both glad that I did! We previously used one of those hook/clasp products to store our shopping bags. The problem with that product is; it hangs from the stroller handle and with only a couple of bags it would cause the stroller to tip backwards (mostly when my son would get out of the stroller) but still a hazard if you're doing a lot of Christmas shopping.
The Space Maker secures all the bags against the back of the stroller, keeping the weight over the wheels. No tipping, even when he jumps out of the stroller! We had his diaper bag, 2 very large Macy's shopping bags and a couple smaller bags all stuffed into this thing, and still had our hands free for coffee. My son was able to get in and out as he wanted, and the stroller never tipped.
I love the simplicity of this product! And my wife has already ordered another one for our other stroller.
Also, it's nice that it can stay attached to the stroller even when it is folded. You may have to detach/re-attach 1 or 2 hooks, but it's basically there and ready to use (or not use) at any time.
If I had to come up with a negative... It would probably be a little better if the solid panel in the center was just a little bit bigger. This would help keep a more uniform shape when you have it stuffed full. But this product well exceeded my expectations, so it still gets all 5 stars!
FYI - this is the only product review I have every written on Amazon - if that tells you anything.
