ULANZI SK-23 review buyers usually want one thing: a compact suction solution that feels practical instead of overbuilt.
Based on the listing, this model is aimed at creators who need a quick mount for cars, glass, desks, and other smooth surfaces.
SK-23 Review Summary
The ULANZI SK-23 is best understood as a focused accessory, not a full rig.
It gives you an electric suction base, a 1/4-inch screw hole, and ARRI locating holes in a very light package, which makes it appealing for people who want a simple way to mount a small camera, action camera setup, or phone on a smooth surface.
Its strongest case is convenience.
If your shooting style involves moving between a windshield, dashboard, window, tile wall, or desk, the SK-23 is built around that use pattern.
The listing also emphasizes vibration resistance, which matters for driving, off-road footage, gym content, and time-lapse work where a passive suction cup can feel too uncertain.
At the same time, buyers should read the constraints carefully.
The suction cup is the product, not a full mount kit, so the package does not include the arm, action camera adapter, or phone clamp.
That means the SK-23 makes the most sense for people who already understand their mounting ecosystem and only need the suction base.

Key Features and Specifications of SK-23
The SK-23 is an electric suction cup mount from ULANZI built around smooth-surface attachment.
The listing positions it for use on sunroofs, dashboards, side windows, windshields, desks, treadmill screens, tile walls, and glass doors, so the target use case is broader than just car filming.
Its physical simplicity is a core selling point.
The product weighs only 56 g, which is unusually light for a mount accessory that is still meant to handle action-camera-style use.
ULANZI also claims it can hold up to 1 kg+, though that figure should be treated as a manufacturer claim rather than an independent test result.
The attachment interface is more flexible than a basic suction puck.
You get a 1/4-inch screw hole for mounting cameras and related gear, plus ARRI locating holes for compatibility and anti-twist positioning.
That matters because a suction base is only as useful as the rigging options around it.
Another practical detail is the power and release workflow.
The listing describes one-press instant suction, a side air release button for detaching, and Type-C charging with a built-in battery.
In other words, this is designed to be a reusable powered accessory, not a manual suction cup you reset by hand every time.
Here are the main listing facts buyers should note:

| Mounting | 1/4-inch screw hole, ARRI locating holes |

Pros and Cons of SK-23
Pros
- Very compact and light. At 56 g, it is easy to keep in a small creator kit.
- Fast setup. The one-press electric suction design is meant to reduce setup friction.
- Flexible mounting interface. A 1/4-inch screw hole and ARRI locating holes broaden compatibility.
- Useful for multiple shooting environments. The listing mentions cars, home setups, gym content, and time-lapse use.
- Modern charging and release workflow. Type-C charging and a side release button fit everyday use.
Cons
- Not a full kit. The package includes only the suction cup, so many buyers will need extra parts.
- Best only on smooth surfaces. If your use case involves textured or uneven materials, this is not the right tool.
- Manufacturer claims need context. The stated 1 kg+ holding ability and vibration resistance are helpful signals, but they are still listing claims.
- Narrow specialization. If you do not need suction mounting, the design offers little extra value.
Who Should Buy SK-23?
The SK-23 is a strong fit for creators who already know they need a powered suction base rather than a general-purpose tripod or clamp.
It makes sense for car videographers, mobile vloggers, action-camera users, and people setting up quick mounts on glass or other smooth indoor surfaces.
It is also a reasonable choice for buyers who value low weight and fast deployment.
If you move gear between locations often, the compact design is easier to live with than heavier mounting systems.
It is less compelling for first-time buyers who want an all-in-one solution.
Because the package excludes the arm, action camera adapter, and phone clamp, the SK-23 is better for people who already own compatible accessories or are comfortable building out a modular setup.
You should probably skip it if your shooting surfaces are rough, textured, or highly irregular.
The listing is very clear that it is built for smooth surfaces, and that limitation is central to how well it will perform.
Why the SK-23 Works for Surface Mounting
Electric Suction Matters
The electric suction design is the headline feature because it changes the experience from manual tightening to a quicker press-and-go setup.
For repeated car, desk, or glass use, that is a real convenience advantage.
Compatibility Is the Real Selling Point
The 1/4-inch screw hole and ARRI locating holes make the SK-23 easier to integrate into different rigs.
That matters more than flashy marketing because the suction base itself is only one part of the system.
Portability Fits a Creator Bag
The 56 g weight keeps the accessory nearly invisible in terms of kit burden.
For travelers or creators who want a mount they can carry without thinking about it, that is a practical benefit.
Surface Limits Define the Use Case
This is not a universal mount, and that is not a flaw so much as a design boundary.
It is built around smooth surfaces such as windshields, glass doors, tile, and desks, so the buyer should judge it by that standard rather than expecting broad material compatibility.
Alternatives to SK-23
If you want a more complete suction-based setup, look at the SmallRig suction cup mount for a broader accessory ecosystem.
If you already use action cameras, the GoPro suction cup mount is a familiar route.
For buyers who want a camera support brand with a long accessory catalog, the Ulanzi suction mount family is the closest comparison point.
If your priority is vehicle filming specifically, car suction camera mount searches will surface many variations with different arm and clamp combinations.
The right alternative depends on whether you need just a suction base or a complete mounting solution.
The SK-23 is strongest when you already have the rest of the rig.
Is SK-23 Worth It?
The ULANZI SK-23 is worth it if you want a lightweight electric suction base for smooth-surface mounting and you already have, or plan to add, the rest of your camera support parts.
Its appeal is not completeness; it is speed, portability, and a focused feature set.
If you need a ready-to-use bundle, this is probably not the best first purchase because the suction cup is sold alone.
If you want a compact mount component for car, glass, desk, or other smooth-surface work, the SK-23 looks like a practical buy.
