ULANZI Stretchable Tablet Clip ST-20 Phone Holder (2289)

Review

ULANZI ST-20 (2289) is a universal sliding holder designed to securely hold smartphones and compact tablets in filming, streaming, online lessons, and everyday work. The key idea is to quickly, without tools, fix the device in the desired orientation and just as quickly integrate it into your existing setup: tripod, light stand, tabletop tripod, bracket, or "mast arm". The design combines a spring-loaded sliding mechanism with additional fixation, and inside there are soft anti-slip pads that protect the case and glass and dampen microvibrations when touching the screen. Thanks to standard mounting interfaces, the holder easily "makes friends" with most accessories without adapters.

Ease of use

ST-20 is made on the principle of "slide - insert - fix". The spring quickly picks up the device, and the fixation brings the fit to a monolithic one. This is especially important when you work with your finger on the screen - the tablet/phone does not "walk", and the frame does not shake. Standard threads allow you to instantly rearrange the holder between a tripod, tabletop support and light stand - without adapters and screwdrivers.
Quick orientation changes save time in social media content: horizontal for YouTube/presentations, vertical for Stories/Reels/Shorts. If the setup includes a ball head, tilting and micro-correcting the angle takes seconds — convenient for an over-shot over a table, a conference, or a video tutorial.

Functionality

1. Reliable fixation - a spring clamp with "adjustment" ensures a tight fit without creaks and play.

2. Two orientations + micro-angles — quick flip to portrait/landscape, precise tilts via ball head.

3. Universal mounting - 1/4" threads are compatible with most tripods, mounts, and mast arms.

4. Stability under the touch - soft pads dampen microvibrations, the screen does not respond with "shaking".

5. Working with cases - the holder's "jaws" are designed for typical silicone/polyurethane cases.

6. Quick relocation - move the holder from a tripod to a tabletop stand or light stand in seconds.

Compatibility and scenarios

• Smartphones of most brands and sizes — from compact to large models.

• Compact tablets - provided they fall within the sliding range and maintain weight balance.

• Streaming and video communication — Zoom/Teams/Meet, vertical broadcasts on social networks, webinars.

• Education and demonstrations - video tutorials, hand-held broadcasts in a fixed angle, document camera.

• Content making — top-down cooking/DIY photography, gadget reviews, timelapses from the table.

• Retail and events - tablet/phone as an info-terminal or light/sound control panel.

Tip: If you are working with heavier devices, place the holder on a more rigid support (a stand/tripod with a wide base) and compensate for the angle to reduce the "leverage effect".

Design and ergonomics

The ST-20 case is tightly assembled: there is no play in the hinges, the spring stroke is predictable and uniform. The internal pads have a pronounced texture - they firmly hold smooth glass surfaces without leaving marks. The geometry of the "legs" is designed so as not to block the power buttons, volume rocker and microphone holes; if necessary, the device can be moved in the clip by a few millimeters.
The 1/4" jacks are positioned so that the power/headphone cables do not conflict with the support. The planes are parallel - the holder is easy to place flat without "drifting" to the side. The relief on the controls helps to work with gloves and wet hands.

Advantages of purchasing

• Quick start - installation without tools and adapters.

• Out-of-the-box compatibility - 1/4" standard opens up most tripod ecosystems.

• Reliable grip and protection - soft pads, anti-slip edges, stability to the touch.

• Format flexibility — portrait/landscape, angle micro-correction, working with covers.

• Easy integration — quick relocation between supports, saving time on location.

• Mobility - compact and lightweight, convenient for daily carrying in a bag/backpack.

Where to buy

The model is available in photo and video stores, electronics chains, and mobile accessories departments. The package may vary: sometimes only the holder is supplied, sometimes in sets with a tabletop tripod or adapters. Choose proven sales channels for correct warranty support.

Care and warranty

To make the ST-20 last longer:

• periodically clean the pads from dust to maintain grip;

• do not overtighten the fixing elements - a tight fit is sufficient without excessive force;

• do not leave the device clamped in direct sunlight for a long time;

• during transportation, reduce the clamping to a minimum so that the spring does not get tired;

• Avoid overloading thin supports - choose an appropriate stand/tripod.
  Warranty terms are provided by the official seller according to their policy.

User reviews

Users note that the ST-20 noticeably speeds up preparation for filming and streaming: the smartphone or tablet is fixed in seconds and does not shake when touched. They praise the work of the pads - the device holds securely even in a case. Among the tips is to leave a small gap near the cable connectors, and during vertical broadcasts, make sure that the "jaw" does not cover the front camera.
