Got the Z15 delivered today.  Initial thoughts:
 
1.  Keys are not as noisy as my TTe Sports Brown switch.  They are nice to the feel...Don't have to press as hard to get a response. 
2.  A little disappointed in the RGB.  I like solid blue...but by itself, the Blue is a bit washed out.  When set to RGB...this keyboard really puts on a light show.  Light surrounds the keys as well as coming through the letters.  My old keyboard had light just through the letters. 
3.  Trying to remap keys for a few games that require WSAD is not working.  I like Up arrow, down arrow, left arrow and right arrow.  Trying to figure out how to change them is touch.  Manual that comes
with the keyboard doesn't explain anything about it.
4.  I read some people's reservations about the 4K polling rate and it possibly effecting getting into the bios setup of a computer...NO issues at all with that...
5.  The Unleash software pretty easy to use...just need to figure out key remapping...and I will be happy. 
 
All in all a pretty nice experience
 
Just the beginning...

Honestly...I hardly notice it.  The lights pretty much hide it in the background.  I am pleased with the build quality  My TTe Sports was hard plastic.  The face on this keyboard is metal.  The lighting is very attractive.  As I said earlier...I have my every day Profile 1 in Static Blue.  My Gaming profile 2 is breathing between white and blue.  Nice stuff.  The MSRP is pretty much there with Corsair, Razor and more.  I actually like that the keyboard has built in memory...so once your  settings are uploaded...you don't need to keep the software running.  With Razor...you have to log into your account with them before your profiles load.

How are the media controls? Does the volume wheel have some friction to it? I personally think that Razor's and Corsair's look a lot better but it's relatively minor and their keyboards are much more expensive. I know I complained about the K15's MSRP but I think mechanical keyboards, in general, are too expensive.

Overall, the media controls are decent.  Not too much friction with volume wheel...but it doesn't spin freely.  Agreed that all mechanical keyboards are expensive, but I have been using one for over 5 years now and am so used to them...can't go back to membrane.  The Unleash RGB software is pretty nice.  Very functional and one of the keys to it, for me, is that I am left handed and use the arrow keys to move forward, back, left and right.  WASD is very awkward for me.  I have some games that I acquired over the years that don't have keyboard remapping built into them.  With Unleash RGB, I created a second profile just for those games.  Mapped Up arrow to remap to W, and so on.  Now I can play the games like all the rest.  There is macro assignments, and many others.  As I said earlier...the other benefit is that once you apply the profiles to the memory on the keyboard...you don't have to run Unleash RGB in the background.  More pleased the more I play around with the keyboard.

I'm considering getting it but I already have a Corsair K70. Still considering it since at the elite price, it's a steal compared to other mechanical keyboards since it's from a reputable, mainstream manufacturer with great support. Do you know when the elite sale ends and the warranty length on the keyboard?

I have no idea when the Elite promotion ends.  There was nothing wrong with my TTe mechanical keyboard...but I just finished building a new Ryzen machine and a new keyboard was like the Cherry on top of the Sundae.  Plus, I wanted to see how the software would work when having different profiles and key re-assignments.  This worked out great for me. 

Thanks...

I didn't need the TOF or the macro keys.  Just wanted the options it offered.  Went with the silver switches...no regrets.  Much quieter than my TTe Brown Switch.  I watched this video...it actually reinforced what I was thinking:

I do use the remap key feature in Unleashed RGB.  Being Left handed...I always use the up arrow for forward, down arrow for back, left for left and right for right.  I have a few games that I have had for awhile that I never played because they keyboard setup in the game was WASD only.  Now with the remap keys...everything works for me.  The keys on this keyboard are smooth and responsive.  Very impressed so far.  The Z20 would have been overkill for me.

I can understand the "too expensive" part but then after getting one of the Z10 I realized that I like the feel of it a lot more and on that model the 50 million button presses per key really means I won't have to replace it for wearing out unless something gets spilled on it. The old IBM mechanical keyboards from the late 70's are still going strong while modern keyboards normally wear out in a couple years of office work. That said I am upgrading my Z10 to a Z20 just because I like the media controls more but the keyboard itself is still running fine after about a year and a half of use and feels just like brand new.

Hey there,
