PSA: I RMA'd my device and currently waiting for it, so I'll update this review after a few months of using the new and non-faulty device. Will attach images then. I'll probably change this to 5* when I get the replacement KB and if my 2 issues are gone (info below)
I upgraded from my old Steelseries Apex 360, which is a low-profile membrane KB. Keys are harder to press, mostly due to being old
So I appeared to receive a defective product from the following: (1) Duplicate keys (likke thiisss), and (2) Non-responsive keys. I ordered this KB on 7/10/21, and contacted CM Support on 8/12/21. CM Support has been very generous and helpful. My RMA application was approved, and so my faulty KB is currently on the way
Ignoring my faulty KB, so far here is what I love:
1. Extremely easy to clean. If you look at pictures, the keys aren't sitting inside the board, but on top, so junk doesn't get stuck inside the board. Keys are very easy to pop off. Just get a can of air compressor, and it's instantly clean. USBC cable is also detachable from the KB base, so you don't have to unplug it from the PC end and un-cable manage the whole thing
2. Surprisingly quiet and light keys for a mech kb. (cherry mx low profile) I was always hesitant to get a mechanical keyboard because I never liked being loud when typing. This keyboard genuinely surprised me regarding this
3. Material. Soft, firm, definitely not cheap feel. Keys physically feel great, and the board is such a nice, sleek, brushed aluminum material
4. RGB lights both on the keys and under the keys, are very nice, and overall quite bright (good)
5. Compared to my previous KB, SS Apex 350: Smaller than what I had, so more space on my desk, even with the fullsize version of this CM kb. Also no more excessive macro keys, though a few would've been nice. More space efficient. Spacebar isn't jank. Better RGB customization on the physical kb. No external software needed, but if I want to use it, it works nicely
Downsides so far:
1. There's no back feet to prop up the KB higher. This is pretty significant but not enough to not buy it. Only takes away from my experience a little bit. Still surprised about this one
2. No dedicated macros on the KB but that's okay, more of a luxury, not a necessity for me specifically
UPDATE AFTER USING RMA'D DEVICE FOR MONTHS: Experience has been fantastic & it works perfectly. Support was also very good. Changed 4* to 5* rating. I actually got to have the SK652 board with the SK650 keycaps, so now I also have back feet

Customers say
Customers praise the keyboard's appearance, particularly its RGB backlighting, and appreciate its low profile design. However, the build quality receives mixed feedback, with some finding it good while others report poor quality control. Moreover, the typing experience is negative, with customers describing it as a nightmare to type on and taking time to get used to. Additionally, reliability is a concern as keys fail to work properly, and key spacing is problematic with keys being too close together. The keyboard feel and switch sensitivity also receive mixed reviews, with some loving the feel while others find the switches stiff, and while some appreciate the switches, others report double-entry issues.

What a DEAL from Cooler Master!
GREAT DEAL, Got this on sale for $62! This is the SK650 (original model) which I knew had 2 ergonomic challenges. First was the Keys I read some folks don't get used to the chicklet style keys and can't adjust while others can adjust. And second was the keyboard didn't have kickstands in the back to lift the rear of the keyboard which is on most keyboards. This being said I knew what I was buying based on the deal and accepted the known ergonomic shortcomings of this device even though it shines in many other places! It kind of matters to each individual differently in the end. I knew there was a SK652 version which addressed all this too... probably why this on is on sale as they are getting rid of older inventory. That being said Cooler Master included a full key cap kit which this board with allow the user to swap from chicklet keys to a more traditional keyboard cap design which was unexpected and amazing!!! Props to Cooler Master as I wasn't aware they would do this and wasn't expecting to see this! Bonus points to Cooler Master as I have purchased many items from them over the years and was again impressed by this decision they made when they didn't have to! Very Awesome and it made me want to write a glowing review in their honor! :) Added after reviewing the item page: FYI - It is advertised with 2 sets of key caps! This wasn't expected as I read early review articles on this device from review outlets and I don't think this was originally a thing... this shows me Cooler Master listened to the feedback in the newer model SK 652 and decided to include key caps to buyers of this SK 650 model I think... cheers!

Color: Gunmetal blackSize: SK650Style: FullVerified Purchase
Esta genial el teclado, buenos efectos de iluminación sin necesidad de un programa, el sonido de los switches es smooth, es muy fácil quitar las teclas a diferencia de otros teclados, y te incluye también una herramienta para remover las teclas fácilmente, muy bueno. El teclado viene dentro de una funda de tela como de terciopelo muy bonita y venia muy bien empaquetado, la caja estaba dentro de otra caja más grande y envuelta. La serigrafía y tipografía de las letras son perfectas, me gusta los logos que tiene, como en las flechas (parecen como de un auto).DanielMuy buen teclado, lo recomiendo
Reviewed in Mexico on January 5, 2023
Quizás el único pero que le pondría es que no tenga patitas atrás para subirla de altura, ya que es totalmente planito, y pues una ruedita del volumen, pero esto último ya es mucho pedir.
En general es muy buen teclado, tiene buen acabado, se ve muy bien estéticamente, tiene buena respuesta y es entrada tipo C con cable trenzado, para mi gusto no es difícil escribir en él, he visto varios comentarios sobre que las teclas son muy pegadas por lo que te confundes de teclas fácilmente, la verdad es que no, es cuestión de acostumbrarse al cambio de un teclado con diferentes tipos de teclas y switches, para mi gusto es muy bueno.

Nice to type with removable chiclet keys. Wish Coolernaster provided spare chiclet keys with rough texture surface for gaming. USB C to A cable is removable for easy mobility. A velvet keyboard cover is also provided which is nice. Overal a good buy at its sale price. Get it while stocks last and before prices return to retail.
