To be honest, the hash pointed at outside pools is extremely unstable but I'm impressed just by the fact that this system works. For now, I'm only mining in mintsy's pool and waiting from a response from their support.
The hash rate displayed at the website isn't all that stable either but it's not unrealistically low either, if pointing has at external pools worked better I'd be perfectly satisfied.
What about the price? Last time I checked, ROI was almost impossible. Has that changed?
17 USD with a coupon (MINEMINTSY) I used for 100 Gh/s. With the recent offer the hash rate (supposedly) receives a 150% bonus but it's pretty unstable at the moment. I think that mintsy has been around for quite some time, yet the website is still incomplete. The FAQ page just says 'COMING SOON' right now. I'm confident that things will improve a lot since this is just getting started though.
Wait, $1.7 per 10 GHS? That s pretty competitive. What about fees and the period of the contract?
