Tried Surfshark from my location in Malaysia. My main interest was connecting to UK sites BBCiplayer/ITV Hub and other TV Catch Up sites. I took out a months subscription on trial and didn't get good results - continual lag which needed continual re-connection on most sites. I cancelled the subscription and received refund as promised. Later discovered I had problem with my laptop driver which I had fixed and this re-established my laptop fast internet speeds. Because of Surfshark pricing I was tempted to try again which I did, unfortunately with no improvement in the performance of Surfshark. I cancelled again and because I had previously tried there was no refund the second time, something worth remembering because most other companies did offer refunds for 2nd tries.
I accept and think a lot depends on your location but certainly can't agree with Surfshark's 'Blazing Speeds' claims. Of the many VPN's I have tried to replace my expensive Express VPN subscription which is coming to an end, there have been others with much higher speeds. I was fortunate ultimately in discovering one that offered 7 days free trial without creditcard and which turned in the best performance of all I had tried. In the end cheap is not always the best option.
I mainly use Surfshark to torrent and the speed doesn't drop much, but it's also important to use a server that's not overcrowded. As mentioned in the article the price is low even though it offers unlimited device logins which was what made me buy it, but I can now say that the service I get for the price this low is more than worth it in my books. Other than that, my lil sis really wanted to try out Disney+, so I had to help her set everything up. It was a bit messy but in the end everything works fine.
