That's exactly the problem with MANY cheapo mixers that have too large holes<o:p></o:p></pre><pre>for the pot's shaft and these shafts are rocked in all the way<o:p></o:p></pre><pre>with no secure mecanical provision..

Try to imagine.. when you need to pull their knobs for repair<o:p></o:p></pre><pre>you fear of ripping these shaft out of the device..<o:p></o:p></pre>
