Did you see this new product?

Is this shop safe and they deliver in appropriate time or not ?
Does any one have experience before?

Dear friends,

I am new to mining and after mining on my personal hardwares now i decide to run a pool,
I am interested to run a pool with highest quality available, on Gigabit connections and powerful server's hardware with very low latency on one of the best datacenters,

Every one is interested on my pool?

Just if i receive your feedback then i will begin the setup, also i hear your suggestions, i can run pool on both Windows or Linux platforms, i have experience for more than 7 years on web and server development and also i have CCNA certificate on network,
You can rely on my skills
