Your opinion is needed

I am planning to switch to adminvps hosting with powerful VPS servers. Please tell me if anyone has experience of owning European servers?

Pretty much all the providers nowadays come with a money back guarantee. So you are free to explore different web hosts and pick the best.
You can trust hostingsource.com cheap vps. What is so important is you always experience you are not alone dealing with customer or tech support.

I don’t have experience with AdminVPS, but if you’re open to alternatives, DediRock offers powerful VPS solutions with excellent performance and 24/7 support. We are U.S.-based servers might be worth considering for reliability and value.

With the right web hosting provider, your business web site can be much easier than you think.
There are so many web based design tools and marketing tools included in web hosting packages, that you really don't need to know much about html, programming, or otherwise.

All I can say that I am fully-satisfied using NETSHOP Cyprus VPS service.
I'm really happy with their support, they reply support queries very instantly.
