unfortunately the software is plagued with problems so unless you are an enthusiast with skills on tweaking pools and pool software .
They also don;t work on multipools yet which is a big negative in the scrypt game.
I would wait for a new firmware from them. The hardware seems solid though.
If I remember right didn't they split the chip shipment with another company?
And scrypt mining game is a hard one. I loved it during GPU days, but anymore I have mined sha256 and paid for altcoins instead of mining if I want some. If you have to get a scrypt miner i suggest going with one of the A2's. There are 30, 60, 90 MHz models. I highly suggest working out ROI math before any purchase there though.
