The LX-4 plus cock ring is best used when placed around the penis, though it could also be used on non-vibrating dildos to make them vibrate. The ring can be worn when soft or hard, due to the stretchiness of the silicone. Depending on the size of the penis, the ring could provide a slightly larger erection as well as providing deep, thuddy vibrations for you and your partner. Regardless of size, the ring should stretch to accommodate. You or your partner should only wear the ring for 30 minutes at a time. It should only be worn around the shaft and not the whole package. Overstretching the ring may cause damage to the silicone. It is advertised to be waterproof, but it only looks splashproof to me. I am overly cautious, however.

This toy should work for almost everyone. The ring will stretch to accommodate nearly all penis sizes and the vibrations should be strong enough for most people. The ring is simple enough for beginners to use, and can be enjoyed by advanced users as well. It would make a good second cock ring. I say second because it is a lot of money to spend when you don't know if you like cock rings. If you tried another vibrating ring and enjoyed it, I would suggest getting this one. It would be the only one you would ever need. It is travel friendly, because it has a locking feature.

The LX-4 plus is made entirely of silicone, which rates a 10 out of 10 on the Eden Fantasys safety scale. Silicone is food-grade, hypoallergenic, latex-free and phthalates-free. It retains heat and repels water. Silicone also repels dirt and bacteria and doesn't fall apart with extended friction. It is completely non-porous and safe for the body. It can be shared if cleaned properly in between uses and partners.

The material has no odor. It is plushy and stretchy on the ring portion, and firmer up top where the motor is. It is smooth, with very little texture. There is some raised text and a seam, but neither are really noticeable during use. It has a matte finish and only a little bit of drag. I think the material has the potential to pull hair, but we haven't had any problems with that.

Only use water-based lube with this toy.

The design and shape of the LX-4 plus are brilliant. The vibrating portion is large, (larger than its counterpart, the LX-4) and it hits just the right spot. I feel like this portion is large enough to hit the clitoris or perineum of most people, and it should be highly stimulating for the average person. The ring is stretchy enough to accommodate most sizes and remain comfortable, but tight enough to provide a slightly larger erection and stay in place without sliding. Again, I believe it should fit the average person. Definitely adjustable. The toy is easy to take on and off and can be put on when soft or hard. However, it should only be worn on the shaft and not the whole package, because overstretching the ring can cause damage to the silicone. The appearance of the ring is unique, because it provides a larger, flatter play area than most cock rings on Eden. The ring part is pretty typical for a cock ring. It comes in black and has a matte finish.

The LX-4 plus is very easy to operate. It has a steady vibration that starts low and increases to a full 4 vrooms and 1 bee. It has no patterns, but they are not missed. To turn it on, you press it once, then press and hold the button on top to ramp up the power. The longer you hold the button, the higher it goes. Release the button to stay at the level you are on. You can't go from high to low, so to go back to a low level, you will need to turn it off and back on again. To turn it off, quickly press and release the button. To lock, press the button three times in quick succession. Do the same to unlock it.

This toy works very well and is worth the money, in my opinion. The vibrations are very strong, deep and thuddy. Plus, the toy is rechargeable! To charge, find the little hole marked "DC" and insert the charging jack into it very slowly. Once it is in all the way, plug the charger into an outlet. The red LED comes on while charging and turns off when fully charged. When the light goes off, unplug the charger from the outlet and slowly remove the charging jack from the toy. If you pull it out too fast, you might rip the silicone surrounding the charging port and it will no longer resist water.

This ring worked very well for me and my partner. I already enjoy sex, but this made it even better!

To clean, simply wipe down with a alcohol-free baby wipe, or spray with anti-bacterial toy cleanser and wipe with a wet washcloth. Do not boil or place in the dishwasher; it will ruin the toy. To sanitize for use between partners, clean with a 10% bleach solution. To store, put in a small drawstring bag and tuck it somewhere safe. Make sure it is not touching any toys of a similar material.

This is the only cock ring I will ever need. A bit pricey, but definitely worth the cost.
