Sorry to say, there is no good free VPN or even ones that are cheap offering unlimited lifetime subs. It costs money to run this things. Unless you skimp out on servers bandwidth and have a few servers, i dont see how this services can provide a good service.
If you want no logging, high speed servers, you have to pay. If you read across the internet,reddit etc. You will find there are a few top rated VPNS. AirVPN which i use after a long through read before i bought it is one of the best when it comes to security and features. Just try to have a look at their client. I get only 10% reduction in speed compared to without a VPN. With free and cheap ones, you can forget about it.
If you want to pay less, there are some vpns which are usually on sale like torguard for example at 15$ USD for 6 months which is i think cheap enought to try but there speed is decent enough, also there is PIA, might be a bit better in speed than torguard and usually on sale at 32 USD.
Check the usage policy before buying.
