It works fine but you'll make less than on, say, MiningPoolHub. I recently experimented a bit and concluded that while something like AwesomeMiner that will sometimes tell you you're minding Digibyte-Skein at $9/day is exaggerating by quite a bit, you do make maybe 15-30% more on MPH (hard to tell you exactly how much more because the prices keep fluctuating). As a small-time miner with only one GPU though, I think I'll stay with WinMiner because it's far less hassle and it's much easier just cashing out to PayPal than mucking around with exchanging cryptocurrencies.
same here. I have just withdrawn my first 20$ today to Paypal and the experience was fine, great stuff. It was quite easy.
As for balance updates and so on, I reside in Europe (besides the fact that I am not always checking the updated stats) and every time I check the stats update quite fast, but dunno, I am not constantly seeing whether it is updating or not. In addition, this is a great program to keep track of the coins, how are gaining traction a day and those which aren't.
It updated in both my rigs today.
