The Yonex Portable Badminton Court (that is, Net) works like tent poles with stretch-string. It takes about 1 minute to put it together, and the same time to take it apart. It stands well on any surface indoors and outdoors.
I didn't give it the fullest rating because the net isn't the full width of a court; judgment calls regarding a return being 'over the net' when the shuttlecock sails over the court sides must be made.
The net itself is of good material, and it maintains a good posture (not much sag).
This has made Badminton available for my son and me during a homeschool session for exercise and enjoyment. We use it almost daily.

I like it. It is portable and easy to set up and put away. The only thing is, the width is not that wide for a doubles play. Aside from that I am very happy with my purchase. Thanks :) 5 stars

I opened this in the middle of a party. Without looking at the instructions, it took less than 5 minutes to set up. And it's portable enough that you can bring it along to a picnic, etc. Definitely a win, and far less hassle than a stakes-in-the-ground arrangement.

Exactly what I was looking for in a portable net. Set up took just minutes. No stakes to set or poles to put in the ground. It is not a regulation size width however the ease in setup and take down make up for this. 5 stars
