They can be profitable if you have fairly low electric cost as a Litecoin (Scrypt) miner, but they're getting marginal even there unless your electric is well under 8 cents/KWH or so.
The "blades" never were designed for SHA256 mining, they don't have the power capability OR the cooling and WILL FRY FAST if you try.
The "orbs" were designed to dual-mine but the power circuitry was marginal for that.
The "Compaq" stick does not have a European maker but they do have a European reseller.
Are you sure on this? I'm pretty sure it's made in Europe or at least assembled there.- https://bitcointalksearch.org/topic/sales-open-sidehack-stick-official-sales-thread-for-europe-1141518
The site from thread that sales them is - https://www.bitshopper.de/ they also have a amazon but amazon is higher priced since amazon fees.
It's a completely different design for Europe and includes free shipping to some of it and vat included. So price is higher then US version but it is good it's available if your in Europe.
Thanks!
I am now thinking about buying or the Usb that reaches 23gh/s (8 without overcloking) or the miner that gives a hashrate of 63 gh/s.
I don´t pay for electricity and as they cost the same the choice would be clear but;
I have read that it sounds at 25 db (dont know how much that is but will try to investigate);
for my reasons, i can only have that at my room, and... i like sleeping XD.
While an Usb i guess that would do no sound np?
THanks for your reply
Indeed, a compac stick is soundless. But the PC where you plug in the stick might make a sound
