The "Off with their head!" cap is designed to replace the standard hitachi cap. The cap is constructed from 100% silicone, which lends it a softer, more "giving" texture than the standard cap. The nature of silicone is slightly sticky, expect the cap to attract endless amounts of hair and lint. Don't even think about storing it under the bed! You'll discover dust that you didn't know existed. Another aspect of silicone is the slightly plastic-y scent that fresh silicone has. Let the cap "breathe" a bit and the smell will swiftly fade.

The cap is aesthetically pleasing, with nicely rounded edges and eye-catching curves. The cap has parallel ridges on one side and a single vertical ridge on the opposite side. As mentioned previously, the silicone gives more under pressure than the standard cap, which lends itself to squishing beneath pelvises and between bodies.

At first blush, the cap is everything I was looking for: pretty to look at, easy to put on the hitachi, softer than the standard head, and couple-friendly. As for actual use of the product, I was disappointed. Unless you douse your bits in lube, the silicone will catch on skin, covers, hair, etc. Not a big deal for an insertable toy, which I expect to use lube with, but for a toy designed for external stimulation only? Talk about creating a mess. Plus, the ridging gave no discernible increase in sensation for my partner or I.We swiftly found that we prefer the original hitachi cap.

Worst of all, for me, the cap changed my storage habits of the hitachi. I prefer to store my hitachi just under the edge of the bed, hidden by a bed skirt. This is no problem with the normal cap: just wipe it off after use, slip it under the bed, and forget about it until you want to use it again. With the "off with their head" cap, this simply wasn't possible. I could wash the cap two or three times in a row and there would STILL be dust, lint, and fibers on it. Instead of spontaneously reaching under the bed when my partner and I were feeling frisky, suddenly breaking out the hitachi during play became a huge ordeal involving a trip to the sink, a drying cloth, etc. This alone was enough to turn me off of the cap. After giving the cap a few weeks trial run, I had to retire it. I put the cap back in the original plastic cylinder it came in and set it away safely at the back of my toy box. I've not used it since, and don't really have any intention to.

I pulled this cap out of the depths of my toy chest, and I gave it another whirl. I still think that this cap performs poorly compared to the standard Hitachi cap. Without extra lubricant, it drags and catches on the skin (the original cap doesn't). It'll tug your sheets (and hair!) along with it, if you scoot across the bed during use. I find it more inconvenient to use, rather than sexy and stimulating.
