About us

A little over 5 years ago, my Nintendo 3DS broke. I couldn't afford a repair or replacement, so I decided to fix it myself. I discovered in doing so that I enjoy working with electronics and decided to turn it into a side hustle; buying, fixing, and selling old devices so that others can relive (and the new generation can experience) the same joy they brought me as a kid. I've since expanded my business into other categories and also sell some of my replacement parts, so that anyone who wants to fix their own machine like I did can do so affordably.

I take great pride in the quality of my work and in my long-standing reputation. When it comes to buying used or refurbished electronics, I know from personal experience that transparency is paramount. With TKCN, what you see is always what you get, and I accept returns on (almost) all purchases if you change your mind.

Thanks for visiting, and as always: feel free to reach out with any questions!

    Seller was very helpful throughout the whole repair process and answered my questions. There was initially a few delays in shipping, but each delay have a reasonable explanation by the seller. Would buy again from this seller and highly recommend.

    I was hesitant about mailing in my consoles for repair, but I’m glad I did. The work was amazing, and despite delays from waiting on parts and serious family and health matters, they were transparent when able and made it right by comping some of the repair for all four of my consoles. The process took from Sept 2024 to Jan 2025, and while communication could greatly improve, their care and effort won me over. I’d happily do business with them again. Packaging was perfect. Thank you!!!!!!!!!!!!!

    Product was delivered in safe packaging, and works well. In good condition to the one replaced. The specific module I received was from a Japanese system, however, I believe Japanese ds systems are not region locked and the language can be changed. No issue there. Great seller, thank you again.

    This seller knows what they are doing. They did such an incredible job repairing my device and I could not be happier. They were very communicative and friendly, and the cost for parts and repairs seemed fair. 10/10 highly recommend.
