I purchased this MacBook to help complete normal tasks like creating documents, browsing the internet and watching YouTube. Over the first few weeks I noticed the fan cooling the computer was a bit louder than expected but i thought to myself, it's a used computer, it's not going to be perfect. As the weeks and months go on I found the computer working REALLY hard when only a few separate programs were running. Then shortly after, the battery would last less than two hours before needing to get plugged in again.It has been less than 6 months since receiving this computer and I am basically tethered to a plug and have to keep my patience when a multiple programs are running at the same time. The return/warranty window was 90 days and being just outside of that, they are not interested in helping me exchange this for something at equal value - even though the product is clearly at the end of its life. I am not one to write reviews (positive or negative) but I don't want anyone else making the same mistake as me.If you plan to buy a "Renewed Product" either prepare to suffer or plan to return/exchange before that 90 day window closes so you're not stuck in the same situation as me.If the seller sees this and would like to offer an exchange, I'll happily change my review, otherwise I would avoid these used products.
