Not effective and is ADWARE.

ADWARE: It keeps opening ads to buy it's subscription service

Вставляет рекламные баннеры на страницы YouTube, а так-же открывает вкладки с рекламой и фокусирует на них, и использует странные классы и data:image, чтобы предотвратить блокировку. Не могу рекомендовать.

Inserts ad banners onto YouTube pages, as well as opening promo tabs and focusing on them; it also obfuscates class names and uses data:image URLs to prevent you from blocking its popups. I cannot recommend it.

Даже не думайте это устанавливать.

Great

The connection keeps dropping; it's useless.

Не устанавливайте, не работает.

Excellent VPN, works without interruptions

РЕГУЛЯРНЫЕ ВЗЛОМЫ МОИХ АККАУНТОВ, НЕ УСТАНАВЛИВАЙТЕ! DO NOT INSTALL CAUSED REGULAR HACKS OF MY MAIL AND OTHER ACCOUNTS

Works flawlessly so far (been using this one for months), doesn't open any pop-ups or ads, doesn't require to pass captcha or wait to connect, doesn't demand signing up or in, connects and disconnects immediately, offers 6 free servers (although specific countries and their availability changes from day to day).

Sin duda, este es el mejor VPN gratis que he probado, y si decides comprar premium, en buena hora. Muchas gracias a los desarrolladores por crear tremendo programa.

DO NOT USE THIS.

Avast reacted as soon as I installed this. I made an exception (stupid I know, but I thought I could trust Firefox add-ons).

Then, within minutes of adding it I got a 2FA login request for a random work website. This means somebody got the password from my Firefox Password Manager. I ignored this.

Then a while later I got notified that a new Admin user was added to one on my Wordpress websites. I removed this user right away.

THIS MEANS MY PASSWORDS WERE BREACHED.

BAD BAD BAD
