Zoom R12 - Used only once! It was too much for me! Listing it immediately!

From zoom R8 to zoom R12 and back to zoom R8

I've been using the zoom R8 for several years. About a week ago, while connecting a USB cable to the R8 (Mini B), I handled it carelessly, and the R8 stopped receiving power. Even when I selected Card Reader from the R8's USB, my PC could no longer recognize the R8.

I sent it to zoom for repair, and they responded with:
① 
② ...However, they added, 
③ Looking at listings for the zoom R12, the market price is around <37,000 yen for a new unit>. I decided that , and requested the product exchange.
④ Then, the day before yesterday, I received the unit and tried it out just once. However, for recording purposes like my singing and playing guitar or simply mixing backing tracks with vocals, the R12 has far too many features, and I found myself bewildered. I concluded that . I searched for the R8 and fortunately found a used one at a low price on [Platform Name]. So, I immediately listed the R12.
⑤ I put the backing track into the zoom R12, recorded 3 tracks of vocals, connected it to my PC (Cubase), and edited the mix just once. (The recording quality was good). It's still in beautiful condition, and the warranty and account registration remain unused.

I will ship it as it was sent from zoom (Image 02). I have listed it for 32,000 yen (original price 37,000 yen - 5,000 yen discount).
