Chrome extension differences: Urban Shield VS Urban Free VPN proxy Unblocker


What’s the difference between these two Chrome extensions, which provide VPN functionality for browsing via Chrome:

Urban Shield: https://chrome.google.com/webstore/detail/urban-shield/almalgbpmcfpdaopimbdchdliminoign?hl=en

Urban Free VPN proxy Unblocker: https://chrome.google.com/webstore/detail/urban-free-vpn-proxy-unbl/eppiocemhmnlbhjplcgkofciiegomcon

They are both developed by the same company, but I couldn’t find any explanation regarding the differences between the two.
