Not much to say about this except that it is pretty much perfect
The ultrsound dipstick is superbly manufactured and is extremely high quality. The length is perfect for prostate stimulation. It is easy to clean and very easy and pleasurable to use. The 10mm diameter is very good for me.
This is wonderful in operation with an anal insertable. With some careful placement of electrodes you can stimulate your prostate. A feeling like nothing else short of orgasm. Works great and large size fits well for someone who has done sounding or other urethra play. Highly recommend and suggest careful cleaning before and after use.
