1 out of 5 eggsnot what I expected

Pros: compact layout, quiet keys, no ghosting

Cons: at this time, october 23 2012, the drivers for this keyboard have 404d on the adesso website. media keys do not function on windows 7, I dont know if this is because of no drivers or if its incompatible.

the keys are a little too flat relative to the frame and I find it hard to hit the keys along the bottom (my thumb hits the frame instead of the spacebar) and the slightly smaller right shift is more annoying than anticipated

Other Thoughts: this keyboard would be perfect if the media keys worked and the keys came up just a tiny bit more.

3 out of 5 eggsMediocre Keyboard

Pros: Nice, small size. Looks ok. Key layout not overly wacky.

Cons: Key touch/feel seems a little squishy. Function keys slightly smaller and very close to upper row of keys, easy to accidentally hit a function key when reaching for upper row of keys. No right control key. Lettering on keys starting to rub off (sooner than other keyboards I've had).

Other Thoughts: Overall, an ok small keyboard. Just a little disappointed with the keys rubbing off, the squishy feel of the keys, and the proximity of the function keys to the upper row of keys.

5 out of 5 eggsAvoid other brands of the MCK-91 keyboard - Adesso is better!

Pros: Full Windows 7 compatibility, great feel to the keys even a year later, has all the keys I need - no more, no less

Cons: None found, with the Adesso version of the MCK-91

Other Thoughts: I have been using an Adesso MCK-91 keyboard for well over a year now at my main/personal workstation and decided I wanted one for my work/employment workstation across the room. I made the mistake of thinking that a MCK-91 keyboard under the Bytecc brand would be the same or comparable to this one and I found the Bytecc cheaper elsewhere. Out of the box it looked identical, but that is where any similarity ended. The Bytecc MCK-91 had keys that were more "clickity-clackity" than I like, it took some "breaking in" time to get all of the keys to register consistently and the Ctrl key failed within 2 days. I hadn't realized just how valuable the Ctrl key is to me until it stopped working and Photoshop became a pain to use without it. So I returned the Bytecc one and got another Adesso and all is well. In this case, a particular brand name did make a difference and that was the main point of this review. Paying a little extra for the Adesso version was definitely worth it for me.

5 out of 5 eggsGreat Little Keyboard

Pros: It's a small keyboard. It works. It can be stored out of the way.

Cons: None

Other Thoughts: I can't believe people write reviews complaining that this keyboard is too small. It's a mini-keyboard ferchissakes! It's actually the same size as my standard keyboard's main key section, or a typical laptop keyboard.

3 out of 5 eggscute, but...

Pros: Very nice size. Almost as little wasted space as the Apple keyboards. Good keyboard layout. Media controls. Plenty of length in cord.

Cons: The feel of the keys is soft and mushy with no identifying tactile or audible indication as to whether the stroke was registered. Not a professionals keyboard at all.

The first one I received wouldn't always register the "s" key. Newegg replaced it free of charge and no shipping. Newegg is so good in their customer service. Das why we luv em.

Other Thoughts: BE AWARE: This keyboard has a PS/2 plug. Not a USB connection, as is popular today. Also be aware that cheap keyboards like this occasionally have unusual layouts. This one has a good layout, but look closely at the picture of it to see if it will match what you're used to.

2 out of 5 eggsok. Lacks vista drivers

Pros: Reasonably small yet still usable. Nice keyboard.

Cons: I use it on my XP and Linux machines but the Vista drivers don't load (return an error). So it works as a basic keyboard but the multimedia buttons don't work for Vista. Manufacturer does not respond to emails or tech support requests.

1 out of 5 eggsTerrible product, horrible customer service

Pros: Straight forward layout that you'd expect from a mini-keyboard.

Cons: On their site they rate the key switch life (how many times you can depress each key) at ten-million cycles. This is a gross exaggeration. I've had this keyboard for almost three months now and I've come no where near ten-million presses. The problem actually started about a month after I had it. The problem is the membranes they use for the keys break. If you pop off one of the keys you'll see the membrane. It's a little rubber dome with a small collar at the top. This collar tears away from the dome part and the key no longer bounces or snaps back after being depressed. The button just sits in a depressed state and results in a non-functioning key. I suspect poor material selection over poor design.

Other Thoughts: The second problem is their customer service is non-existent. I've never seen their online chat support actually online, the five emails I've sent are all replied with some auto-generated email telling me they received my email and if I have further questions, visit their site. I've tried various times throughout the day to call, there is never anyone actually there to answer the phone. And the past couple times I've tried calling I get a busy signal. Be aware if you buy Adesso; you're getting a shoddy product and no tech support/customer service

5 out of 5 eggsSelf-righteous touch typists need not apply

Pros: Compact size overall, but almost all keys are full size, laptop keyboard feel (e.g. nice spring, less travel and not too "clacky"), square shape (particularly nice if your desktop has a front lip like mine does)

Cons: Not a con against the keyboard, but newegg's delivered price on this - ten bones more than the "black a with orange smily" site

Other Thoughts: I was happy that the touch typists who reviewed this keyboard here gave it poor ratings because then I knew it was the right one for me ;) Most touch typists need standard sizes (read: inflexible) & whine about anything else. This one is pretty close to standard, but the space bar & backspace key are a bit shorter. I can deal with a backspace key that is .75 as wide as normal vs. those keyboards where they make it the standard key size =( Generally, I hit the spacebar in the middle, so that is no different. The other key placement that I am adapting to is the delete key. If I had my choice, it would be the top right corner, but I have already adapted =) In case you haven't surmised, I am proudly a hunt-and-peck typist. One last note: I am not sure if it just XP or if it is because I have Logitech's iTouch software installed, but all of the multimedia keys on mine work without having to install any other software. Most reviews say to avoid Adesso's software, so I did.

5 out of 5 eggsThe Best, as Always!

Pros: I bought several of these within the past 5 years. Don't waste your money on cheaper keyboards (like I did). The only one with wide enough keys.

Cons: None
