I’ve been told to get used ones which is my preference aswell however, my anxiety kicks in with pre owner stuff and I always feel like they will break down. I’ve seen this brand all over ebay with good reviews just wanting to double check everyone experience with this brand.

Yeah I'd stay away. It doesn't feel like high quality. Mine was DOA (broken screen) and error messages. I sent it back, luckily I have eBay plus.
