Very pleased with the Blue Helix. It replaced an older basic series 1 which was fine initially over time was leaving me just a tad short of the output needed for a hands-free orgasm. The Helix has just that little extra OOMPH to get me over the edge. Do miss the extra output plug which allowed more versatility, like a sound or anal egg plus two pads.
ADMIN: The extra socket was removed as it caused a lot on confusion with customers who assumed that it was a separate channel rather then a second output. If you wish to still have a second output you can use a dual adapter.
