Thanks to djeZo's leasing concept (official thread : https://bitcointalk.org/index.php?topic=414009 ) , I'm just starting to rent my four miners !!

Thanks you also for my first customers.

For information, I have noticed that my connection stability (see on leaserig.net) was not good at the beginning and after a check in my side, I have turned off background program like windows update or bitcoin client to avoid connection lost.
For the mining side, I didn't notice any connection problem on all the workers, if customers can confirm that with their actual pool.

Best regards
