Yes. Also the caregiver can push if he ever wants but for those patient who doesn't really- cannot use the hands anymore, and they need the help from the caregivers, so they can- the caregiver can push them. Instead of using their hands. So that is one of the features- of the benefits of this wheelchair. Now we- we are talking about these, how to fold if you on board. For example, you are on board, how to fold it, you can use you hand from here to go here and you fold it and you start raising for this. You're raising for this one- you raise this and you take it out. And then it becomes more smaller. Now this one is about 14- 14kg, but if you take it out, this one and this, then it's only about 10, then about 10.6 kg. So at least you have more space on board if you're travelling, by packing up this one. When you put it in, you can just press it like this and you can just push. And it's just a very quick thing. And you can put this like these, like that. This and this one. Okay. And you can detach and hold it. It's very easy. It's very comfortable. Now once you open up, you can just do it like this. And you can do like this. You always hear the clicks then you open up like this.
