Tested for 6 weeks with 9 devices simultaneously.
Base speed: 500 Mbps fiber. Surfshark’s WireGuard protocol averaged 395 Mbps (21% loss). Nearby servers (same country) gave 460 Mbps. Long‑distance (US to Europe) dropped to 310 Mbps.
We connected 9 devices: 3 Windows PCs, 2 iPhones, 2 Android tablets, a smart TV, and a Linux laptop. All maintained stable connections. Speed on each device remained above 280 Mbps when simultaneously streaming.
Surfshark unblocked Netflix US/UK/Japan consistently. BBC iPlayer worked intermittently (sometimes required server switching). Disney+ and Amazon Prime worked fine. CleanWeb blocked most ads and trackers on all devices.
Surfshark has a strict no‑logs policy audited by Cure53. Features: CleanWeb (ad blocker), GPS spoofing on Android, and obfuscation (Camouflage mode). Kill switch works on desktop.
