Really like this site--it's clean, no ads or popups/popunders to chase down and close. It was really easy to get started, I think this site is a really great way for someone new to mining to get started.
I don't usually mine Monero for other people because the pay rates are so low, but I've made an exception here. I've got some old hardware collecting dust that's now mining on CoinGrabr--saves me from having to exchange Monero to BTC.
Best part is, for me (I'm lazy), it pays directly to your Faucethub.io account. This also means you can monitor the faucet on FH and I've never seen this one go dry.
Thank you for your work on this site, CoinGrabr.com!
