The ability to see how my website will look across different browsers/platforms was great! It's difficult when I'm working from home because of COVID-19 restrictions but it allowed me work remotely while at our local library or coffee shop - which helped immensely during these times where social distancing has been required by all Americans due to this pandemic situation!! Nothing really as far concerns their service goes; however there are some minor issues like using Google Chrome instead Safari (since most people prefer safari) would make things easier since they're both very similar programs yet one works better than another browser wise if used correctly? Also having an issue uploading files via FTP server through Filezilla after logging onto feature peek account then attempting upload file again gives error "FTP connection closed". Please try other software such as Cyberduck before purchasing your own private cloud.
