Summary: Been using these classic keyboards for about 15 years, but I have to agree with some of the others~ they wear out. I'm willing to live with them, however, because I love their heft (they don't move around on the desk) and their key action (sort of feel like a good ole IBM Selectric).
Pros: Solid, heavy-duty feeling, love the key action.
Cons: The letters wore off in about 3 months. The spacebar didn't last a year. The free Dell keyboard this replaced lasted almost 5 years. At $33 I expected a whole lot more. Cheaper alternatives last longer and perform just as well.
Pros: 1.) good Feedback/Tactile response for a membrane switch. 2.) Varying level of resistance depending on the key. 3.) Pretty Sturdy 4.) Standard Layout and Keys (no small keys you see on a lot of slim keyboards these days)
Cons: 1.) Keys are a little wobbly 2.) Is louder than most membrane keyboards 3.) The etching feels like it may wear off for a while
Cons: Incredibly overpriced. This is not a mechanical keyboard, despite some reviews that might lead you to think it is. You can pop off any key and see the membrane underneath if you cared to check. The keyboard isn't even "clicky", it has a very soft feel on keypress. The tactile response is very low...
Summary: If you like the classic long throw and spacing of an IBM Model M without the clickiness, this keyboard is for you. Great for gaming as well!
Pros: Has the best key action I've ever used. And I've owned just about every mechanical keyboard out there. The Keytronic Classic is like nothing else. Been using the same one for over 5 years now, daily use.
Cons: The lettering on the keys could be more durable.
