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!

    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!!!!!!!!!!!!!

    Item arrived as described. I believe it was a quality item, but packing had an issue that resulted in the screen being rendered unusable. Id say partially my fault but not 100%, ribbon cables where stuck to very strong double sided tape making removing them without damage tricky. I reached out to the seller about this but a week later i haven't recieved a response. Probably not a big deal, i dont think everyone will encounter this issue. Ill just chalk it up as a learning experience and move on.

    Apologies for the inconvenience and thank you for your feedback. An influx in demand has caused significant lead time in replying to messages, so I'm sorry I didn't see your message before seeing your feedback. Thanks again for your care in mentioning this, and I will make a concerted effort to resolve this issue moving forward :)

    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.
