— cringelord67 (Canada, Verified Purchase, December 2017)

“Solid compact keyboard and Corsair quality. Cherry MX switches smooth and quiet. Substantial feel, hefty build. Overall impressed.”
— amzn shopper (USA, Verified Purchase, May 2019)

“There are not many keyboards that are Mechanical with Cherry MX Reds, TKL, and have backlighting. If you like red this is perfect and doesn’t get cheaper for quality. Should last a LONG time.”
— Will (Australia, Verified Purchase, February 2024)

What Customers Warn About:

“Ridiculous pricing. Even the full-size one comes 3k less than this. Keyboard is good but not worth 13k considering much better alternatives at this range.”
— Vineet (India, November 2021)

“Import from Amazon US website—it’s cheaper. Heavy rip-off to customers buying directly.”
— Kumar Rishav (India, October 2019)

Key Takeaway: High satisfaction (88% positive) when purchased at fair price ($79-109 USD in 2017-2019), but regional price gouging and discontinuation have shifted value dramatically. Most negative reviews cite pricing, not product quality—until long-term reliability issues emerged.

— Source

Battery Replacement Options:

Official Route:

• Under warranty (2 years): Contact Corsair support for RMA replacement
• Out of warranty: Corsair states battery is not user-replaceable

DIY Route (⚠️ Voids Warranty):

• Keyboard uses standard 18650 Li-ion cell (3.7V, 2,600mAh)
• Requires disassembly (multiple screws, plastic clips)
• Reddit users have documented the process: https://www.reddit.com/r/Corsair/comments/j4yxe0/k63_wireless_keyboard_battery_replacement_has/
• Risk: Permanently damaging keyboard PCB or housing clips

CAUTION

Technical Note: If the charging LED doesn’t light up at all when plugged in, the issue may be the internal charging controller (IC) on the PCB, not just the battery cell. This makes DIY repair significantly harder, as it requires PCB-level soldering skills or board replacement. Simple battery swaps only work if the charging circuit is functional.
