I own and operate an SP10 and two SP30s. Totally brilliant units. Spondoolies-Tech gear is top notch "server grade" equipment, and their customer service is the absolute best that I have encountered in the industry.

Just so you know, I've been mining 24x7 for the last 444 days*, and I also own gear from ASICMINER, Bitmain, Bitmine, BFL, and KnCMiner.

Since Spondoolies-Tech started selling miners I haven't found myself purchasing from another vendor. Not saying I won't (I quite like variety), but ever since I got my first SP10 I've been addicted to the build quality, form-factor, efficiency, and customer service.

And yes, they have always shipped on time. They cut it fine with the August Group buy, but I did personally receive my SP30s in the month of August, albeit at the very end of August... but still August. Some other companies (I won't mention who) will keep telling you that they will deliver in Two Weeks™, and deliver 6 months to 1 year late (you think I'm joking... I'm not). Then of course there are the scams that take your money and never deliver a product.

_{* I calculated the date I started mining and by pure chance as I post this it is 444 days since then.}
