Refurbished 3DS XL didn’t work, and then just…did

Hi everyone! I need a little advice. I just received a refurbished 3DS XL in the mail. Condition-wise it was fine. A little scuffed, a little dirty, a very small faded spot on the screen, but once I cleaned it up, overall perfectly acceptable for a 10 year old refurbished console.

However, once I turned it on, the issues seemed to mount. The touchscreen was very finicky as I went through the initial setup. Sometimes being very responsive, sometimes not at all. However, it was working great by the time I got to the main menu. Then, I noticed that the d-pad and Circle pad seemed to be on the fritz. I would start to navigate down the icons when it would suddenly stop and start navigating backward.

At this point, I put in for a return. However, just as a Hail Mary I put a game in to see if the buttons would work better in-game. That's when I found the next issue: The card reader seemed broken. I got it to register the game for a second, then it disappeared. Eventually, I got the game to launch, only for it to say "Card Removed" a second into the game. This happened a couple times until I restarted the system again.

Which is when things got really weird, because lo and behold, everything started workiung perfectly. Buttons all work. Touchscreen works. Game reads and loads up. No issues as all. My question is this: has anybody ever had anything happen like this before? Do you think I should hang on to it for a few days and see if the issues come back, or just go through with the return now? It wasn't cheap per se, but it was a very fair price for a limited edition system in decent cosmetic condition.
