Far superior to the battery operated versions!
I have had the battery powered Emjoi for a while, and while it gets the job done, I have been frustrated by the awful screeching noise as the rollers stop spinning with the slightest of pressure.  This corded model works great while being considerable less noisy.  Also, while the mfg advises against it, I have had no trouble whatsoever from gently rinsing the rollers and using the accompanying brush if necessary.  I would recommend drying them thoroughly before re-use, however.
