Here are a few comparisons between Mullvad VPN and Nightshade. note that there are several others, but these are the most common:
Mullvad is a highly-advanced VPN service that is very secure and reliable. It does not limit how many devices you can connect. It has no ads and allows torrenting. It is very user-friendly, and it is affordable. It has a 30 day money back guarantee and a 7 day money back guarantee. The main disadvantage of this VPN is it doesn’t have a free trial. However, the customer service is very good, so there shouldn’t be any problems in using Mullvad VPN.
Netshade is also a very good VPN service. It has a 30 day money back guarantee, 3 simultaneous connections, unlimited bandwidth, and unlimited data transfer. Just like Mullvad VPN, Netshade also has no ads and allows torrenting. However, it does not have a free trial for the first month of using the service. It also has a limited free version of the software which limits bandwidth to 500 MB per day.
