Good because once they're on, they're basically invisible. Bad because initially trying to put them on, they're invisible ;)<br>
They work very well with the <a href="http://www.sparkfun.com/products/9117" rel="nofollow">rotary encoder</a> that's offered here. Much better than the <a href="http://www.sparkfun.com/products/8828" rel="nofollow">other knob</a> I purchased which fit very poorly, hindsight >= 20/20.<br>
The size of wrench I got to work was a H1.5, but I wasn't super scientific about it. Also when putting it onto the rotary encoder above, be mindful of the depth. If you put it on all the way, you don't get any room for the push button action. So go all the way & back it up 0.5mm (tiny) so you can use as a PB, or don't, I really don't care.</p>

I want to know if it would be safe to use this knob on an encoder that is not SELV. The isolation rating of COM-09117 is only 50V.</p>
