The LX-4 plus is the slightly larger and more powerful version of the LX-4 rings. It's rechargeable, water-proof and made with super-stretchy silicone (to fit most penises whilst still being snug and enhancing the male erection) but falls short on delivery.

Vibrating cock rings can be used individually or with a partner and can enhance sexual intercourse for both parties. Basically used on the shaft of the penis (not the testes) the LX-4 plus can also be placed on a dildo for additional play options. Being made entirely from matte-black silicone it's very consumer friendly and easy to clean between uses.

The vibration setting is excellent and being rechargeable makes this product worthwhile however, the manufacturer states that the ring should not be worn on a penis for more than 30 mins and the battery, in practice, actually lasts less time than that. I've used other vibrating rings which are rechargeable and last for 1 to 1.5 hrs of use AND also have a remote control for hands-free play. The vibrating head is large and powerful and can be positioned to stimulate the clitoris or perineum of most people.

The vibration doesn't have pattern settings but can vary intensity the longer you hold the button down. You can also lock it by pressing the button three times. The lock feature is very clever and makes this little device travel friendly however the hold-to-increase feature, lack of patterns and remote make controlling this ring very, very difficult.

The charging plug has country adapters to be used in various countries but again, I've used other rings which recharged with just the USB connection - which is much, much more convenient.

Although the LX-4 plus is a great first vibrating cock ring for solo/couple play it's certainly not the best and the exceptionally short battery life (and 2 hr recharge time) makes this an impractical purchase considering other options.
