[Open Discussion] Do you buy refurbished tech?

Tl;dr: buying a refurb phone was a waste of money.

I agree with the points made earlier about not knowing how well the previous owner treated the device and difference in price being cancelled by the need to by a replacement battery.

I personally bought a second hand iPhone to replace my old android and from the start the battery only lasted 4-6 hours depending on use; I even had to keep it plugged while using it at one point. Then, the charging cable it came with stopped working and (as I was on holiday) I had no choice but to buy a replacement cable.

After all that, I had to get a new phone anyway and it's served me without issue for years.

So IMO, just buy new if it's something you know you'll need to depend on. Buy things like furniture and jewelry secondhand.
