dfk41 I stumbled on Coffee Nerd Arron when I was looking at the CafeSing Orca, seems like a nice guy, but he got some things wrong & there are some pretty big omissions in that review.
External adjustment moves if touched whilst grinding - not mentioned.
Machined burrs are ‘bimodal’, no evidence that the ghost burrs are not also bimodal (all hand grinder burrs are bimodal if you set them fine).
Grind time with ghost burrs is ‘really not that bad’ …it’s ridiculously long, Two and a half minutes at a coarse grind, compared to about a minute for Feld/Comandante.
Claims the surface area of the 49mm ghost burr is greater than a 64mm electric grinder burr - basic lack of maths.
The grinder does have 4 detents between settings at 14-15, but the numbers are physically wider and there is a wider spacing between them at the higher range, Where you will be using the ghost burrs (around 5) there are only 2 detents between each number and 3.5 to 5 pretty much covers the useable range.
When you fit the rubber bands to the grinder body (which you will, to avoid nudging the adjustment ring) it shortens the available hand space, so your hand doesn’t quite fit, which is a bit awkward.
Didn’t mention the highly variable dose consistency at all.
The CafeSing is interesting, it doesn’t ‘not work’ but it is definitely not a grinder to buy if you are only intending to have one £190 hand grinder.
