The Gtrsiow Gp-2in1-17s, marketed as a Plug and Play Star Projector Night Light, aims to transform any indoor space into a personalized starry night sky. This budget-friendly device caters to users seeking an easy way to create ambient lighting for bedrooms, kids’ rooms, or small gatherings without a complex setup. It is a straightforward projector that relies on physical theme slides and USB power to generate its cosmic effects, but its notably low user rating suggests potential buyers should temper their expectations regarding build consistency and optical clarity.
This review will provide a detailed analysis of the Gtrsiow projector’s specifications, design, and features, supplemented by direct excerpts from verified purchaser feedback. We will assess its suitability for creating relaxing atmospheres and decorative lighting, while addressing the concerns highlighted by its mixed reception. The bottom line: this is a highly portable and versatile device on paper, offering multiple visual themes, but its real-world performance appears to be inconsistent, making it a consideration primarily for those seeking basic projection on a budget who are willing to accept potential quality variances.

Design and Build
The Gtrsiow Gp-2in1-17s projector is designed for simplicity and portability. It features a compact, palm-sized body constructed primarily from plastic, with a base diameter of 3.5 inches and a total height of 6 inches when assembled. The white shade sits atop a black base, conforming to a modern style. Its most distinctive physical feature is the 360-degree bendable flexible hose that connects the lamp head to the base. This allows users to manually adjust and fix the projection direction toward ceilings, walls, or other surfaces. The design prioritizes ease of placement on tabletops, and its small footprint makes it easy to store or transport.
The build quality, as indicated by the materials list, is functional rather than premium. The plastic construction contributes to its light weight and low cost but may also factor into durability concerns raised in some user reviews. The physical design includes a push-button switch for operation. The included components are the projector unit itself, 17 theme slide discs, and a user manual. No specific power adapter is listed, as it relies on a standard USB connection for power.
Performance and Features
Visual Projection and Slides
The core functionality of the Gtrsiow Gp-2in1-17s revolves around its projection capability. It is equipped with 17 interchangeable, high-definition theme slide discs. These slides are designed to project various patterns onto surfaces, including starry skies, nebulae, and ocean scenes. The projector operates in a dual-projection mode, though the specifics of this mode are not detailed by the manufacturer. The light is produced by what the manufacturer describes as premium, flicker-free LED beads, intended to emit a soft, non-glare glow to protect eyes during extended viewing, such as overnight use as a night light.
However, performance in this area appears mixed according to user feedback. Some owners praise the “rich colors” and “clear projection,” while others report that the image is “fairly blurry” and that the device lacks any ability to focus the projection, which limits image sharpness. The size of the projected image is also noted by one reviewer as “not that big,” suggesting it may be best suited for smaller rooms or more intimate projection areas. The variety offered by the 17 slides is a key selling point for customizing ambiance.
Connectivity and Power
This projector is designed for plug-and-play use via a universal USB power supply. It does not have an internal battery; instead, it must be connected to a USB power source such as a power bank, laptop USB port, or a standard USB wall adapter. This makes it highly portable, as it can be used anywhere a USB power source is available. The specified wattage is 5 watts. The reliance on USB is a significant advantage for users who want to use the device in various locations or with portable battery packs.
Usability and Controls
Usability features include multi-level adjustable brightness, allowing users to set the light intensity to their preference, which is valuable for creating a secure sleeping environment or adjusting to different room lighting conditions. The flexible hose is a practical feature, enabling precise aiming to cover a desired area with the starry visuals. One noted usability drawback from a user review is the absence of a dedicated on and off switch, implying control is managed solely via the push button integrated into the unit, which may cycle through modes or brightness levels.
Setup, Support and Ownership
Setup is designed to be minimal. Users need to insert a chosen slide disc, connect the USB cable to a power source, and use the push button to turn on and adjust the device. The flexible neck can then be manually positioned. There is no software to install or wireless pairing required. The manufacturer lists a warranty, described simply as “1,” though the exact terms and duration are not specified in the provided data. For spare parts, the EU availability duration is noted as 2 years, which may indicate support for certain regions.
Ownership appears centered on the accessory slides provided; there is no mention of additional slides being sold separately. The device is an all-in-one unit with no listed upgrade options. Support would presumably be handled through the manufacturer, Gtrsiow. Given the product’s positioning as a decorative item and gift, long-term support expectations might be limited.

What Owners Say
Owner feedback for the Gtrsiow projector presents a stark contrast in experiences, which is reflected in its overall rating distribution. A significant portion of reviewers report extremely positive experiences, describing the projector as an “absolutely great value for money” that creates a “dreamlike stargazing pavilion” with “rich colors” and a romantic ambiance. They praise the flexibility of the neck and the visual effect.
Conversely, a nearly equal portion of feedback is highly critical. Common complaints include the projector “broke within minutes” of gentle use, citing poor build quality. Others note functional shortcomings like blurry images due to a lack of focus adjustment, a smaller-than-expected projection size, and the desire for a more conventional power switch. The polarity in reviews suggests significant inconsistency in unit quality or performance, making individual outcomes somewhat unpredictable.

Who Should Buy It (and Who Should Skip It)
The Gtrsiow Gp-2in1-17s is best suited for budget-conscious users seeking a simple, portable device to create customizable starry night effects in a bedroom, kid’s room, or for small-scale party decor. Its USB power makes it ideal for those who want to use it with power banks or in locations without convenient wall outlets. It could serve as a novel gift for someone who enjoys ambient lighting without high expectations for optical precision or long-term durability. If you’re interested in other tech that enhances your personal space, our reviews section covers a wide range of products.
Potential buyers should skip this projector if they require a sharp, large, and finely focused image for detailed ambiance creation. Those looking for a robust, long-lasting device for daily use over many years may be disappointed based on the concerning durability reports. Users who prioritize a premium feel, advanced features like remote control or timers, or consistent performance across all units should consider other options with higher ratings and more established feedback.
Final Verdict
The Gtrsiow Gp-2in1-17s star projector is a product of contradictions. On paper, its specifications are appealing for a budget ambient light: 17 theme slides, USB portability, a flexible neck, and adjustable brightness. These features offer genuine versatility and convenience for creating a starry atmosphere. However, the aggregated user feedback paints a picture of inconsistent quality control, with a high incidence of units failing quickly or delivering subpar, blurry projections. This discrepancy makes a definitive recommendation challenging.
Ultimately, this projector represents a gamble. When it works as intended, it provides good value for its low cost, serving as a fun decorative piece or sleep aid. But the risk of receiving a defective or poorly performing unit is non-trivial, as evidenced by the rating distribution. Buyers should proceed with caution, perhaps leveraging a generous return policy. For those needing reliable tech, exploring our tech gear recommendations might yield more consistent alternatives.
FAQs
Does the Gtrsiow star projector have a remote control?
No, the product specifications and user manual description do not mention a remote control. The device is operated manually via a push-button switch located on the unit itself. This button is used to turn the projector on/off and likely cycles through the brightness levels.
Can I use this projector without the slides, as a plain light?
The product is described specifically as a projector and night light. While it might emit a diffused glow without a slide inserted, its primary function is to project the patterns from the included theme discs. Using it as a plain, non-projected light source is not a featured or recommended use case by the manufacturer.
What size area does the projection cover?
The manufacturer claims it can “cover the entire room with starry visuals,” but this is subjective. One user review explicitly stated “the image is not that big,” suggesting the projection is best suited for smaller rooms or for creating a localized effect on a wall or ceiling section rather than illuminating a large space uniformly.
Is the brightness enough to use as a night light for a child?
Yes, the adjustable brightness is a key feature marketed for this purpose. The manufacturer states the flicker-free LEDs emit a soft, non-glare glow designed to protect eyes and help maintain a secure sleeping environment. Parents can use the lower brightness settings to provide a gentle, comforting light throughout the night.
