So far so good. High proxies has been a bit hit or miss not only for myself but for a few. I have not had the horror story experiences that some around the forum have had, but everyones experience varies. They are .40 cents cheaper with the standard pricing, and you get another 10% off using that code.
To be honest, I think both are just resellers, however I think that of the two, HighProxies would be reselling Proxy-N-Vpns proxies. With High proxies, around 50% of the time I get an "was that you" verification. With Proxy-N-Vpn I have only gotten that once, and that was me testing a theory and logging into a new IG across multiple devices in the same day before adding to a proxy.
I've been testing them for a month now for various accounts/purposes. I use a high end one for other reasons. I am currently surfing the web with it on:
And the proxy is being used for my IG account.
No noticeable lag, however I always choose a proxy with a local IP.
I have a theory I am testing about using all available forms of traffic sent through the proxy so that it looks more "trustworthy" than your average IG being run on a proxy. IG can easily see your traffic, so if the proxy is just only passing IG traffic, then it is easier to flag as a fake user or bot.
Anyhow, check them out, I like them.
