Forex signal service. good or bad?

I subscribed to a signal service 2 months ago and it has been extremely good for me. I am thinking about subscribing to their 1year service.
I’ve made 400+ pips last week, and i am up 270 pips this week.
But I have a couple of questions first. Is 2 months period enough to test a system? What else should i ask them about? 850 pips a month on average - is it really good or most good traders make more?
Thanks
ps. you can see their ad on Ebay if you type forex manager in search (username: forexhelp). Read what they offer and let me know, please.

moderators, let me know if it’s against babypips.com policy to post something like that. Is it considered to be an advertisement? I just need an advice that’s all.
thank you

Seems to be a run on signal services lately infiltrating forums looking to harvest emails for free…:mad:

And they just keep coming. Another one popped up less than two hours ago — Orange-Something-Or-Other.
