I bought a keycool 87 keyboard from Qtan's store. It took 10 days to ship to my location, though 2 of those days the keyboard was sitting at the shipping agency's nearby storage location over the weekend.

Below is a picture of how the package looked when it arrived.


Back.


Unpacking.






Blue switches. I replaced the ESC key with the red keycool key.



Sitting on my desk. It's not as white as it appears in pictures. In real life it has a slight off white color.


Some key alignment issues can be seen (XC and AS)


It's my first mechanical keyboard so I can't compare it to other mechanical keyboards or switches. Compared to my rubber dome G15 the buttons on this keyboard feel more solid. The keyboard as a whole is quite heavy and is well built. The blue switches are quite noisy and feel pretty heavy. I actually expected them to be a bit lighter. Maybe because I was focused more on the plastic part of the switches than the actual springs .
Overall I am happy with the keyboard, it's a good buy for the price. I payed €68 including shipping. There were no additional charges (custom, VAT).

So in summary,

The good:

* Relatively cheap
* Solid build
* Includes extra color keys, key puller and a bag

The bad:

* Uneven key gaps
* Slight spacebar rattling

It will take some time getting used to a mechanical keyboard, but pressing buttons on it is a lot of fun .

Looks nice and pretty clean, and I love windowed caps.
Seems a decent price for an all-white board! Guess Noppoo would be my preference though, purely layout-wise (and the front-printed pbt caps)..
Also it appears to me that the X is printed lower on the cap than the others around them; and the X, C and V seem to have a thinner infill-line used than the others around them...


STILL: Grats on your new board, do enjoy!
and don't come back here for a while, money will roll right out otherwise

Cheap bastards didn't want to pay Helvetica fees. Probably didn't whql for the domed win key.

Hostilities ...

I like the bag.

This one?

Haha. Noppoo was my first option actually, but they just went out of stock when I wanted to buy them. So I decided on the keycool, since the only other option was to go for much more expensive hardware. But it worked out fine for me since I'm very happy with the keycool and I saved some money. I guess I haven't developed the high standards you guys have (yet).

I was actually a bit worried when I saw the package, thinking that the keyboard might have been trashed, but fortunately it was fine. Apparently mechanical keyboards can take a beating .

I'll see if I can do a short video tomorrow for those whom are interested how the keyboard sounds in action.

Hmmm, this is the Filco copy that has 2KRO right?

Otherwise it looks good, but 2KRO kills gaming.

according to this ebay listing it has 21KRO
http://www.ebay.de/itm/Key-Cool-87-Mechanical-Gaming-keyboard-Cherry-MX-Blue-W-White-body-/300684703509?pt=PCA_Mice_Trackballs&hash=item4602347715#ht_3153wt_1011

Uhm no, this has 21-key rollover over usb (with ghosting) So at least 6-kro.

quote: "Over roll: 21 key over roll under USB and Full NKRO under PS2."

Yeah, apparently 21KRO - funny number! qtan seemed fairly confident it was done in a way that's compatible with all OS, but that remains to be seen...

tobo - any chance you could dump the descriptors so we can see how it's doing the 21KRO?

Here you go, I will add it to the GH thread as well. I have no idea what it says so please let me know what you find.

Keycool 87.rar

Thanks! That's a standard 6KRO report descriptor Was it the only device showing under that port? If you select the Port entry in the tree USBlyzer puts all the descriptors for that port into the Properties window, that will give us some more info

how did you get the sum of KRO keys? where is the information?

Crap, It showed 2 keyboards, probably did something wrong. I'll try again.

Alright, here we go, take 2.

I think my mouse was interfering (Roccat Kone [+]) since that one can be programmed to be pretty much any key or combination as well.

CeeSA wrote:how did you get the sum of KRO keys? where is the information?

First I should say that this is the KRO for the USB communication, so we are assuming that the keyboard itself is NKRO (has diodes etc). In that case the limiting factor is the USB comms.

Err... that's the same single report

In that case I am at a loss. In aquakey it shows a lot more, but for some reason it doesn't register F2, F3 or F6 :S
It does work everywhere else though.

EDIT: Doesn't this board send two seperate packages to enable higher than 6kro?

Yes, most likely it uses multiple devices.

You need to highlight the Port in the tree, not the HID device. The USB Properties view will then begin with Connection Status etc. Like this...



Then the export from the USB Properties window gives a much longer dump, which includes all the reports from all the (virtual) devices attached to that port...

Why don't you just do the #KRO test that Microsoft has so we know for sure if it's more then 6KRO.

indistinguishable. When this happens, that the pattern is ambiguous, the typical keyboard stops reporting new key presses to avoid reporting the wrong keys. We call these unreported key presses, "ghosted."

I recall calling that 'blocked'. Ghosted would be what would happen in case they were not blocked by choice. IIRC.

That test has worked just fine on my Noppoo with NKRO over USB, my filco with NKRO over PS/2, my Quick fire rapid, MK-80, Cherry G80-8113, Topre etc etc.

Wasn't attacking their programming skills, just the proofread ones.

Forgot to say Congrats on Your First Mechanical Keyboard.

And don't sweat the wobbly keys thing.

There is often key/switch variance. It's just a LOT more visible when you have white or colored keys.

McRip Effect (as long as it is only appearance, not performance)

Sorry, haven't checked this thread in a while . I've added the descirptor as attachment for those that requested it. I checked the above microsoft page and the keyboard seems to register up to 21 keys. However I normally use the keyboard over ps/2 interface, since my motherboard has one.

Also here is a short typing test I did on the keycool. I'm not a fast typist so please ignore my crappy typing skills. The image goes blurry towards the end due to shaking of my webcam, sorry for that.



Thanks ripster, I don't mind the small imperfections, still loving the keyboard . Typing on a rubber dome keyboard really feels weird now, keys seem smaller and they lack the nice feedback.

Nice vid! Like the ol' Cherry Blue ClickClack, my fav switch.

Yeah, don't sweat the forum epeen little things I say.

Btw if you get a Logitech LogiCOOL Japanese version mouse you'd have the COOL twins!

Some weird stuff right there . I think I'll stick with my razer abyssus.
