I like how easy it was for me as an individual researcher (not part of my university) with no previous experience in this area to upload papers directly into arxiv from our own servers at work without having access or rights over them first - which would normally be required by other services such as Mendeley etc., so if you're using your employer's network then definitely use! The interface could benefit greatly from being more modern looking/styled but otherwise works well enough when used correctly. It takes time getting familiarised with its features since there are many options available within each function; however once one has become accustomed they can do quite complex tasks very quickly compared to traditional methods where much slower computer systems were needed along side multiple steps taken manually via paper forms and emails between colleagues.
