Turning a round door knob can be an impossible task for people with weak hand grip. That was how I got trapped twice in the same accessible toilet at the Penang International Airport a few years ago. Since then, I have a phobia of using toilets with such knobs affixed to the door.
Most of the doors in the house have round knobs, too. I should replace all the knobs with levers but never got around to doing it. That was why the bedroom doors were seldom closed. I was afraid I could not turn the knob to open them.

The other solution, short of replacing the knob, is to install adaptive devices called the door knob extender or door knob turner to the knob. These devices make it convenient for people with weak grips to turn the knob by way of a lever. They are difficult to find in Malaysia. A lot of online stores carry such items but they are rather expensive.
A few weeks ago, while I was browsing at the newly-opened Daiso at 1 Utama, I found a door knob extender for RM5 only. All items at Daiso are priced at RM5. What I like about this extender is that it is easy to attach and remove. All that is need to slot it into a knob and turn. My only gripe is that the lever is rather flimsy as it is hollow.

When I went to Daiso again, they had run out of that particular device but had another that was smaller. I bought one to see if I could actually use it because it looked a tad too small for a comfortable grip. After attaching it to the door, I found that it has a more solid feel to it and provided a better grip despite its size. This one is going into my wheelchair bag for those accessible public toilets that still use the round door knobs.
