Powerful little mixer and surprisingly quiet.  I was actually able to carry on a conversation while using this mixer.  I did not see/ pay attention to the hexagon and round beater insertion tips and the impression on the main body.  Unfortunately, this still did not help with the difficult to push eject button. I was afraid I had broken it when I finally got them to release.  I would still use this mixer, but if someone has weak hands/ thumb it is probably not for them.
