The small plastic sleeve in the battery shaft was awful. But the Key Io over all it a very nice bullet and would recommend to a friend.

The Key lo is a mini vibrator that is discreet, inexpensive, and gets the job done without a whole lot of fanfare. Its pretty, removable silicone sleeves up the quality above other pocket vibrators and make it versatile for nipple, clitoral, and water play.

The Key Lo was a Low point for us, we wouldn't recommend this one. The name would suggest powerful vibrations, but with one AA battery, it's hard to expect too much.

I love the colors and the idea of the 2 sleeves, sadly that's about all I loved. For the price it was not what I expected.

The Io just didn't do it for me. I would not recommend it to any of my friends, unless they were extremely sensitive and could not handle a stronger vibe. Still, I would probably recommend something with a bit more functions for the cost of this toy. Jopens attempt to provide quality toys at a lower price is a good gesture, but the design on this toy in particular fell short of my expectations.

Jopen's Key Io is an updated and classier version of the basic hand-held personal mini massager. It offers two removable silicone sleeves for the user to experiment with; however, it can also be used without them. A simple one-touch operation and one steady speed keeps things simple, yet interesting, as it offers 5 stimulating patterns to awaken and unlock the senses.

I was so excited about the Key line that I just had to have one of the toys they were offering. I decided to go with this one. I like the fact that it came with two different sleeves to choose from. Plus the toy itself. Sad to say just from playing with it by hand I was not satisfied. I did some quick touching as well and only found one speed that I would use. My first luxury vibe was a total dud. For the price of $50 dollars you can find something way better to use than this.

Stink, stank, stunk. Okay, so maybe I've been watching How The Grinch Stole Christmas too much, but seriously, the lo was a letdown. I was anxious to give this "mini massager" a try but it just didn't work out for me. For the quality of vibrations and material, I'd say it's overpriced. The only thing that makes this a "luxury" vibrator is the silicone sleeves.

This one just doesn't live up to the expectations. It is louder than the others and it doesn't carry the vibrations well, they are more buzzy than rumbly. I wouldn't suggest this one for the cost. You can grab a charm instead.

The Io seems to be the low end of the high end, or the high end of the low end. It has great packaging, materials, and colors like high end toys, but weak, buzzy vibrations that are only one speed like low end toys. Really, I get the feeling that it's just a mediocre toy that Jopen wants us to believe is a luxury item.

The Io is an okay toy, but doesn't live up to the price tag. The sleeves are a bit loose, especially when you insert this toy, and the power button is easy to hit when thrusting with it. It does have 5 settings, but only one of those is a solid, power setting. While it might be for some people, I think that there are a lot better toys out there for $50.
