It's not great but I'm typing on an SK-8820 now. Pretty good for a rubber dome. It's reasonably sturdy and heavy and stood up to my use in a dusty environment all day long for about a year. Still going strong.
One interesting thing it has huge rollover. I don't use it for gaming so I don't really care but I was surprised what the test said.
Reading this and seeing one for sale I bought one on a whim the other day.
It fails asx on the N-key test.
Will do CTL-e-a-s fails if you add the x.
Other impressions:
Good:
It's heavy, looks sturdy etc. Good in a fight then.
Will do w+a+tab (nwn key combo I use) and up arrow+right arrow+ctr; (flatout2 key combo I use). Both of which my old keyboard won't.
It's quiet (good?)
Bad.
It feels mushy... really mushy compared with my logitech internet keybaord (also rubber domed) that I have been trying to replace.
The left ctrl key will only depress if hit on exactly the center. Otherwise it sticks.
I pulled it out and had a look but it doesn't look like there's much that could go wrong... seems more like a design fault than anything else.
I swapped the two ctrl keys but that didn't make much difference.
So yes, wasn't really impressed. I would recommend the old Logitech internet keyboard (model Y-ST39) over this. Much better feel, keys don't move sideways or stick. Makes a good solid clack when bottoming out and hitting the spacebar. The logitech does have huge issues with roll-over though.
I'm going to have to try a mechanical I think. I think I have an apple one lying in a cupboard somewhere that feels quite good (wonder if it is mechanical... should check I suppose) but the connection is the same as that of a phone.
