Price / pleasure disappointing:

For him:
Exciting to be able to "zap" Lady at any time ... but the LEDs on the remote control are white and VERY FEW DISCRETE therefore difficult to use in a dimly lit place discreetly.
Not tested the approval limits.
The 12V battery for the transmitter is provided. (I said as I looked in vain for the info)
The strength of the protection of USB (for charging) of the receiver is to review: torn on first use.

For her:
Already I string provided is not suitable for large sizes (44 and over) and the receiver does not adequately in place in another string.
The vibrations are a little weaklings: titillate yes, get it up to 7th heaven not.
The operating LED (white too) will go to Mrs. an airliner if it gets skirt in a dark place: we see flashing across the string !!!

Fun, yes, but at that price I expected much better!
