What customers praise

Customers praise Proton VPN for its strong privacy features and transparent policies, which are often cited as reasons for choosing the service despite performance issues. Some users appreciate the availability of free servers and the ability to use the app across multiple devices. A few mention that the interface is clean and easy to navigate, even if the underlying performance is lacking. These positive points are consistently outweighed by complaints about speed and reliability.

Practical takeaways

For users prioritizing speed and stability, Proton VPN may not be a reliable choice. While it offers strong privacy protections, the performance issues make it difficult to use for everyday browsing, streaming, or work. Users are advised to test the service thoroughly before committing, especially if they rely on consistent connectivity. Those in regions with strict internet restrictions may find it ineffective. Consider alternatives if fast, stable connections are essential.
