    We intentionally placed the Vac-U-Lock Vibrating Dual Density Ultraskyn Set with Remote as the top choice for a Vac-U-Lock attachment.

There are two Vac-U-Lock bases; one is a swivel plug, and the other is a vibrating plug with a wireless remote controller and USB recharging.

    Best Value

    Our Rating: 4.9/5
    Quality: 5/5
    Design: 4/5
    Ease of Use: 5/5
    Recommended For: Everyone

    Why We Picked It

    The Vac-U-Lock Supreme Harness with Wireless Vibrating Plug is one of the best-value Vac-U-Lock items you can find in our store. The kit comes with a strap-on harness that is fully adjustable and has an open-crotch design that allows more freedom in movement when you use it and, of course, easy access to your rear and your front. The plug included in the kit is compatible with all Vac-U-Lock dildos and anal plugs, so you can use it however you want it. We like the feeling the harness provides, as it has a neoprene front plate that is very well placed, and the kit also comes with two O-rings, so you can use it with other dildos/anal plugs that are not Vac-U-Lock compatible. But the piece-de-resistance is the vibrating option, as the Vac-U-Lock plug vibrates, comes with a wireless remote controller, and is USB rechargeable.

    Who It's For

    The Vac-U-Lock Supreme Harness with Wireless Vibrating Plug is a terrific choice for many, as the strap-on harness is universal and compatible with all dildo models and can turn any dildo into a vibrating dildo.

    Vac-U-Lock Smooth Silicone Dildo Attachment

    Best for Beginners

    LELO ORA 3 Oral Pleasure Stimulator

    Our Rating: 4.7/5
    Quality: 5/5
    Design: 4/5
    Intensity: 4/5
    Recommended For: Everyone, Beginners

    Why We Picked It

    The Vac-U-Lock Smooth Silicone Dildo Attachment is incredible and so smooth to use, and we had to include it on our list, as the dildo fits all Vac-U-Lock plugs. We love the seamless silicone surface that feels amazing and is compatible with water-based lubes. Also, the shape of the dildo attachment is universal, and you can use it for vaginal and anal penetration. But we especially love the flared base that prevents over-insertion and can double as a suction cup base that will stick it to most smooth surfaces.

    Who It's For

    We believe that the Vac-U-Lock Smooth Silicone Dildo Attachment is a good choice for beginners who are just getting into using Vac-U-Lock toys.

    What Customers Are Saying

    LADIES AND GENTS, BE PREPARED cause this thing requires a lot of lubricant. And when I say a lot I mean A LOT. But when you get going with it the dildo feels SOOO SATISFYING. It is simple and effective. Just what I want and need after a long day of work. - Sam

    Why We Picked It

    Wow, the Vac-U-Lock Deluxe Suction Cup Plug is a genuinely incredible and versatile product. It is a contraption that combines a super-strong suction cup that sticks to most flat surfaces and allows you to use any Vac-U-Lock compatible dildo hands-free. The suction cup has a quick-release tab for easy repositioning, and the entire base attaches to a swivel mechanism on which sits the Vac-U-Lock plug. We found it fun and versatile to use, as it swivels and locks into different angles for your convenience.

    Who It's For

    We recommend the Vac-U-Lock Deluxe Suction Cup Plug for everyone looking to efficiently use their favorite Vac-U-Lock toys hands-free.

    What Customers Are Saying

    - Good when I'm tired of using a strap on

    This is a nice option from having to use my Vac-U-Lock dildos only as strap ons. Gives me a lot more direct control and coordination, as well as different options for additional stimulation with my other hand. - Anonymous

    - Great suction cup

    This arrived nice and fast, has good suction and stays on the wall well. Carries all my toys large and small. Only draw back is the locking screw does not stop the head rotating at times. - Anonymous

The set features all you need to have for pegging – a sturdy, high-quality strap-on harness that you can adjust to different waist sizes. Next, three silicone pegging probes fit most users. There is also a Vac-U-Lock plug for the harness and a Vac-U-Lock suction cup that allows you hands-free use. We are impressed by the versatility of this set, as it also comes with three O-rings that will enable you to use any other pegging dildo or anal plug with the harness.

    Recommended For: Everyone

    Why We Picked It

    You think this is a simple handle. Well, it is much more than that, as the Vac-U-Lock Handle is designed in a way that allows you multiple ways to use it. First off, it is compatible with all Vac-U-Lock dildos and plugs, which allows a few extra inches of reach when you use them. The shape of the plug is ergonomic and comes with a textured surface for easy grip. But you can also turn this around and use it as a firm, insertable toy, which we found incredibly convenient. It is made from body-safe PVC and allows easy use of any dildo, even with lube on your hands. Speaking of lube, this is compatible with water and silicone-based lubes.

    Who It's For

    The Vac-U-Lock Handle is an excellent choice for everyone looking for a simple yet practical handle to use with their Vac-U-Lock toys.

    What Customers Are Saying

    - Love the extra reach

    I love this, because I have short arms and I am plus sized. Sometimes it is a little hard to get my favorite dildo inside myself. This attachment gives me at least 8 inches of extra reach. - Anonymous

    Why We Picked It

    We chose the Vac-U-Lock Ultraskyn Cock with Ultra Harness for two reasons – the dildo and the harness! The harness is adjustable and comfortable, and apart from the Vac-U-Lock plug, you can also use it with any O-ring compatible dildo or pegging toy. The Vac-U-Lock plug also doubles as a suction cup base, so more versatility! You get to choose between a 7-inch and an 8-inch Ultraskyn dildo with balls for a more realistic look or deeper penetration. These are comfortable and satisfying and provide you with a lot of play options.
