Just got mine, so far all I've noticed is the left side of the Enter key doesn't really depress or click, but still performs function. Other keys see fine, though shift key doesn't fit too well in hole (showing key struts).

Mine came with firmware v3.3 but I didn't see an announcement notice.

How about some proofreading and corrective actions? ;)

Try loosening the inner screws.

That's because it wasn't published until a few minutes ago -- it's there now.

I've received a DM42 from the recent February 2018 run. Nice - but keys are stiff. I also had the ENTER key issue where it only registers if you press on one side of the ENTER button.

I can confirm that it is possible to fix, as I read in this forum thread, by adjusting the right hand side screw (when looking at the opened back) till the ENTER key registers when pressed in the middle. It now takes a bit more pressure triggering the ENTER key in this way however.

My tweaking (talking about subtle 1/8th turns of the screw now) got the ENTER key to a point where pressing "off centre" left or right still registers, but without the tactile click. Clicking off centre is not as reliable as the big forceful centre click but it usually works.

My overall feeling of the entire keyboard is that that the keys are very stiff and require more pressure to use than I would like. The ENTER key now that it is 'fixed' requires even more pressure than the other keys - I guess because underneath we are trying to push not one, but two switches with a single wide button. And as reported already, the force required to press some keys on the extreme left or right columns may cause the calculator to tilt microscopically - nothing really to worry about, but not ideal.

I'm wondering if the key feel of my DM42 is typical or whether I need to re-align something. It feels like the keys are centred ok. I wish the keys required half the amount of force to trigger. Am praying to the "wearing in" gods now...

I got my DM42 for Christmas - to start with I had the same extremely stiff-key behaviour that you describe, with a few of the top-row keys needing extra-hard pushes to register - but I've been using the calculator each day since then and everything has settled down. All keys work reliably, and the push needed no longer seems unusually hard - either because the keys have "softened" with use, or because I have become used to using them.

Overall I'd give the keyboard in its current state 4/5 - not 5/5 purely because of the ENTER key feeling strange when pushed on the left-hand side (although I never noticed this until I read about it in this forum).

(My personal preference is for Casio-style keyboards - no "click" feedback, but 100% reliable in use. I realise that sales of the DM42 would have been in the low single figures if SwissMicros had followed this route!)

And to think folk mocked my preference for landscape form factor!

I think the keys do soften over time. I've had a beta unit since April or May last year and I also have one of the first run of production units. There is a marked difference in pressure requred between the two. The beta unit strikes me as far more "comfortable" now that it is well and truly broken in.
