But MK brand cost just as much if not more expensive than that.

I have never tried the Ikea one. But the MK has very rigid and heavy plastic. The spring mechanism inside is not loose also. Even the one i had that had for a few years & its exterior plastic yellowed still clicks and works. But that time i remember buying this for RM23.90 at some electrical shop. I also have those RM2.90 cheapo ones. The mechanism always breaks and the outer plastics will be brittle. If you drop it, chances of it cracking is high.
