I have used the free version of Hoxx for many years and it was decent but over the last few months they removed all the servers we can access, it's down to 3, not the 50 they say on their web site. Getting greedy, it's a shame. Was ok, not any more.
In a nutshell - Don't bother!

Не регистрирует .

Если вы пишете "полностью бесплатное приложение", то оно как будто бы не должно предполагать дневной лимит трафика с последующим отключением. Убогие обманщики

Какой же вы VPN, если сразу сходу требуете предоставить вам мой email? Вы кто такие, чтоб я вам его давал? Мне нужен от вас VPN и всё. Сведения собирайте с других. Сношу к чертям.

говнище полное, не работает. пидарасы требуют указать личные данные, чтоб мать твоя сдохла нигер

i'm sorry, your add-on isn't good enough. it's working good but expensive Upgrade (1 week= $4). not recommended, i don't trust it anymore... because my credit card cannot pay for unwanted add-on.
and what is "Free forever"? i think everyone should upgrade it every week - year.
it's scam.

не работает

мошенники... бесплатные сервера работали ровно один день, потом резко все оказались заняты. Предложили перейти на премиум, оплатил, ни один из премиумных серверов не работает!
they are scammers, beware and avoid! free servers lasted exactly one day, then out of sudden became overloaded. I was proposed to switch to premium, payed for it, but NOT A SINGLE PREMIUM SERVER WAS WORKING! this is bullshit or scam. Put your money elsewhere.

seems very untrusted, it's rebranded as SetupVPN?

Extension is very bad. Only 3 countries available and even they don't work well.

The worst proxy i have ever used, i don't want to make an account and let me use a email generator, you are not important enough for me to use my personal email.

Used to be pretty decent. In the last month or so it only has the option of choosing three countries, UK, USA & Germany.

Not good at all. Uninstalled!

Take a guess what i'm goner say... Yes 1 pathetic star for you.

It is useless without Russian server.
