[What is making me freaking angry is following:]

So.. finally I've decided to buy 2 of those A10 Ethmaster which should make 485MH/s consuming only 750Watts @wall.
Stats are that both of them are using 910 Watts each on efficiency++ mode (which is the one that should consume less) and in fact they mine with an average of 450-460 MH/s. So far.. so good. No problem with that.

What is making me freaking angry is following:

There is no goddamn way to mine using a wallet or mining address as your worker. Yes, exactly, you got it. That's freaking stupid! That restricts you from using any pool (like ethermine.. nanopool.... etc. etc..) and so far.. the only pool where I was able to mine is F2POOL where you have to register to their website and they give a username, which is then related to your wallet registered on the website when you login. That's freaking username mining and not wallet based mining.  Very useful for US.. or EUROPEAN miners that have to live with a good 5-10% rejected shares due to very high pings. You know.. china is geographically far away and i'm forced to use F2POOl since that's the only pool which I am able to connect. And yeah... there's also the 2,5% fee to the pool! (I mean.. that's still 1,5% more than ethermine or nanopool!!).

WTF!?!?! Really, was it so difficult to specify on the website that there's no wallet mining?!
BTW, after several mails to Innosilicon asking for a quick firmware update they gained some time by writing.. "I checked with our engineers but sorry to get back with no positive response. Apologize for the inconvenience."
That's all. No solution available.

So, all in all, don't buy it until this issue is considered history.

P.S: Anyone who wants to see facts.. no worry. I can post screenshots.
P.P.S: Anyone who's in my same situation.. start making some pressure on Innosilicon.. maybe there will be a firmware update to solve this matter.
P.P.P.S: Made several edits.. i was actually too nervous to write it down correctly.
