I have 2 of these and they were super handy and neither of mine minded. They weren't in it for long but there were times when it was vital that they were secure up off the ground and I could still have my hands free.
Even though their feet are hanging, they are fully supported the length of their body underneath.
A drawback is that it is not possible for them to go to the bathroom while in it so while they say it can be used for a walk...I wouldn't want to do that.
Fosters and Smith used to carry them for less than $20. I'm not sure if they still do or not though.
