I got the GX Brown version and been using this for 3 days. So far so good. Previously I had HP GK100 which was a complete waste of money.

The noticeable thing is the keys are very responsive and silent (if you like the clicky sound gor for Blue).

I saw some are complaining about the small size, well I find it very compact for me and I like it this way. If you want a wrist rest, go for G513.

And lastly I am not a very competitive gamer so can't tell about the precise actuation but for aver...

Awsm

Almost perfect keyboard, only issue is that onboard memory can only store static effects not dynamic light effects(can use presents stored already in memory though). Rest the keyboard is sturdy, tactile feedback is good and RGB is pretty bright.

Best mechanical keyboard this price range with RGB.

Worth every penny, awesome experience for gaming and work.

Pro:
1. RGB lighting is great.
2. Tactile keys are nice and springy.
3. Build quality is perfect.

Con:
1. Would have liked a little bigger key caps.

PROS:
1. Great RGB, vibrant, non-spilling, looks pretty dope and not gamery.
2. Great software. Ghub has become very stable and reliable.
3. Looks very professional and classy.
4. Great brown keys. Loved them.


CONS/Notes Before you buy:
1. No wrist rest, keyboard ends where the key ends. Causes unwanted keypress.
2. Keycaps are kinda small, causes a lot to typos

One of the best mechanical keyboards I have ever used.

Awesome product by Logitech.
