I'm definitely the minority, but after going through three of them from two different vendors, and having all of them either not work right or at all I will be staying away from shakers from now on.
All three needed the screw across the top tightened to not be incredibly and annoyingly loud and jarring. One never quieted down enough to use, the second did but always annoyed me it was still too much.
The third quieted down nicely and I can see why people might like them but I don't think it's that big of a deal. Of course my third one squeaks like mad so it annoys the crap out of me too. Also one of the holes on the top for the cover isn't threaded so I can't put it on at the moment until I retap it.
I'd much rather have the connector problems others are having, at least its easily fixed. Quality on these are terrible.
