Really? I'm very surprised ???
The first time I used it (back in the 1970s) I found it very easy to clip in and remove.
Removing is a doddle - press the button with your thumb and slide the mic. up with your fingers.
I got it instinctively the first time I used it and thought it a great idea then.
But - remember - this was invented in the days before Hytrel and mic clips were stiff plastic and did not grip the mic. at all. So - when it was invented - it was actually an excellent way of securely holding a mic.
The original clip for the MD 441 also had a sliding button to hold the mic. in so it would not fall out when pointing down.
When Hytrel came along manufacturers redesigned their clips with Hytrel so they hold the mic. tight at any angle. Shure redesigned all their clips and I do not think that any are now supplied with the hard plastic clip that were supplied when they first came out - horrible clips that did not hold the mic. firmly enough and could scratch the mic. with use.
Nowadays mics come with Hytrel clips - even the MD 441 now has a Hytrel clip. It was only the design of the MD 421 that made a large Hytrel clip a bit unsightly (though I think one is available now).
When it was invented, the 421 clip was actually an excellent idea and certainly worked very well originally - but the original 421 clips were made of metal and were better than the modern ones made of plastic.
