Depending on how many you have a company may be a better option. They often offer online drive storage and video files in better formats.
I have that vidvox it works well but like mentioned you need a vhs player with rca output and a computer near the vhs player that has storage space for the files. And the output is in an odd format that doesn't play well on vlc. It can be converted to mp4 but you will need a laptop with some power to convert with any reasonable time frame. That said I have done 50+ tapes with this and it did the job.
