I live in China and use Astrill VPN on my phone and my laptop computer, which is ChromeOS. On my phone, it works fine and always connects. Unfortunately, it is very unpredictable on my computer, often takes a long time to connect to whichever server I use, and often disconnects shortly after I have finally had success. I am not sure how it works on other laptops, but if you have a Chromebook then I would avoid it.
They have locked me out of my account for more than 11 days with no communication and no clear updates about what is going on. They are holding my money hostage and providing no service. This is an evil, spiteful, just overall bad company. If you can avoid them, please do.
I noticed that when I use a Ukraine VPN I opened Google and it is in Arabic. So, they don't have servers everywhere. Just to pretend they have it, but not. Yes, they keep raising the price year after year. I have been using Astrill for 5 years and paid from 75 USD to 120 USD. They don't have a special price for regular customers. THEY'RE NOT INTERESTED IN KEEPING REGULAR CUSTOMERS. Too greedy! I'm done with them too!
