The Isis is made from plastics materials - the core of the body from hard plastic, and the 'business end' a softer velvety plastic composite. What is unique about this material (which is universal to all Emotional Bliss products, and probably proprietary as well, come to think of it), is that it dissolves ever so slightly in water, releasing a small amount (ppm or ppb) amount of a copper ion, which is an effective anti-microbial agent. So in short, a simple water wipe-down will actually disinfect this toy. How cool is that? There are negatives to this, however - the plastic composite is likely porous enough (like most, if not all plastic composites) to make sharing with friends ill advised.
The Isis is the shape of a bullet, with one end flattened to accommodate its push-in-on-off button. It is small - 2.5" long and 0.75" in diameter. It's kinda the same size as my pinkie, although a bit shorter. The Isis has a small bump on its top side , right near its recharge port, which allows the finger sleeves to be attached. Charging happens through a simple plug in port with the included AC adapter, and is difficult to do with the finger sleeve in place. Emotional Bliss, being a UK company, also sells adapters that can be used in areas outside North America, but the North American adapter is all that is included with the Isis.
The Isis turns off and on through a single push in button on its base. This button is not apt to be pressed during use, and is easy to trigger when you want to turn it off or on. The Isis goes at one speed - 80Hz to be exact, which is apparently better suited for younger women (below thirty, if you're curious where that divide is) than the slightly larger 110Hz Chandra. 80 Hz is, admittedly, a bit subdued if you are used to Hitachi levels of buzz, but is actually a nice intensity to use during sex, or elaborate masturbation, when there's a lot going on, so to speak. And on the upside, it's also quite quiet - incredibly discreet and capable of clandestine use behind a closed door.
The Isis runs for up to five hours on a single charge, and more impressively, it holds onto its charge for a crazy-long time. I honestly have no idea what the upper limit is, but I have gone months without picking up my Isis and have always found it still has charge enough for the job at hand with plenty to spare.
The Isis should be cleaned after used with just a with down with water, because it is made of an antibacterial material. A gentle application of soap would certainly be ok as well. Care should be taken, however to clean out the nooks and crannies on the Isis - it has a few seams that may need special attention from time to time. No special attention needs to be taken to its storage, except of course don't leave it plugged in charging while storing.
The Isis comes in a small box that accommodates it, the three finger sleeves, an AC adapter and a small instruction book. No storage sleeve is supplied, although the box is sturdy and plain white, so it could be used for discreet storage if you want.
I have been the proud owner of an Isis for some time now, and can quite honestly say that the only weak point to this toy is the finger sleeves - they can crack, and the small medium and large are hugely different in size, so not at all redundant. Otherwise, this toy is one of the longest lasting rechargeable vibrators I have had the pleasure of using, and the only rechargeable vibrator I have that is *always* charged, no matter what.
I'll say that again, just because I think it's so unique. This Isis is appears to hold its charge indefinitely, so in practice is ALWAYS charged when you need it.
