As I always travel with several kitchen sinks this was a nice, cheap way of making it a little easier. It's quick to put on and take off, and is light and small to carry when not in use. The elasticated cord is strong and pretty secure, but I doubt you can use it if your suitcase only has a single stem on the handle. There are obvious downsides however. If your suitcase is very full, even if you haven't used the extender zip, adding another bag with this strap makes it more top heavy and unstable. Also, I would normally carry my bag on one arm and pull the suitcase with the other, when I used this strap the strain on my arm was quite noticeable and made it really hard work at times, but I expected this and it was generally worth the effort. I found this strap was most useful for keeping everything together and hands free whilst waiting around at the airport and stations etc, but I did prefer to have the straps of my bag over the suitcase handle is it stopped it slipping out of the strap from the side.
