Pros: I have this keyboard and a regular non-stealth mechanical by Razer. In general the function equally, response time, feel, etc.

-Quieter than non-stealth version.
-Fun lighting options to play with, but you'll end up setting it to normal back lighting after playing around for a bit.
-Matte finish help avoids unsightly smudged and finger prints on bezel (older models were gloss).
-Fun lighting patterns to play with, but you'll inevitably set them to "always on" option because they are actually annoying.

Overall it compares pretty close to the regular black widow mechanical, it's just quieter.

Cons: Not a real con, but there are no macro keys to the left of the keyboard. This isn't really an issue, just something it's lacking compared to the previous version.

Other Thoughts: Other reviewers may complain about the noise, but it's a mechanical keyboard... it's unavoidable... It's how they have always been... Go out and test one if you're sure if the noise it going to be too much. The pros far outweigh the cons(there really are non) when it comes to mechanical keyboards.

Pros: Keys are responsive, easy to use.
Very nice backlight effects
Quieter than it's brother
Affordable

Cons: Doesn't look as good as the Chroma

Other Thoughts: Mechanical Keyboards are loud in general, but the Blackwidow Stealth, manages to quiet down the "noise" of a mechanical keyboard (who actually hates the sound). The Blackwidow line of keyboards, both the Stealth version and the basic version are quite loud, but the sound is very satisfying, especially on the Stealth edition. Highly recommend this product if you're looking for a good gaming keyboard as the BlackWidow ranks up near the top out of every keyboard I've tested.

Pros: Heavy, seems well made, back-lit keys and macro capable.

Cons: Noisy....NO....I MEAN REALLY NOISY

Other Thoughts: Being a PC nut for 3 decades having many many different keyboards, I have just discovered the noisiest keyboard on the planet. It's just about bearable until you use the space bar. Even at that, forget anyone trying to sleep in the house if you type normally. If you have a heavy hand, you might want to apologize to your neighbours now.

Tried too hard to be different with the font used on the keys. So different some letters seem unrecognizable.

What was at first a very welcome Christmas gift will be going back, and my 15.00 Logitech will be back doing gaming duty
