Trademark records provide a stronger evidentiary link between the brand and its corporate owner than individual marketplace listings alone.2

SJLERST lacks the extensively documented public corporate history typical of established multinational manufacturers. The earliest substantial public evidence for the brand stems from trademark activity between 2020 and 2021. Shenzhen Yibai Network Technology Co., Ltd. filed the sjlerst trademark in the European Union on 29 December 2020, with registration recorded on 23 April 2021.3

A separate Canadian trademark record indicates an application filed on 18 January 2021, which was subsequently registered or published on 15 February 2023, again identifying Shenzhen Yibai Network Technology Co., Ltd. as the owner.4 These filings establish the early 2020s as the clearest documented starting point for the brand’s international trademark presence.

SJLERST is not the sole brand associated with Shenzhen Yibai Network Technology Co., Ltd. Public trademark records list a portfolio containing names such as Dioche, Dpofirs, Jectse, Goshyda, PUSOKEI, Cuifati, Mumusuki, SUNGOOYUE, and YWBL-WH.12 This suggests that SJLERST operates within a multi-brand e-commerce portfolio rather than functioning as a traditional single-category manufacturer.

The company publicly connected to the SJLERST trademark is Shenzhen Yibai Network Technology Co., Ltd., which trademark databases identify as being located in Shenzhen, China.12 Available evidence indicates that SJLERST is best understood as a Chinese-origin e-commerce consumer goods brand rather than a traditional Western retail brand.

It is important to note that trademark ownership does not necessarily imply that the trademark owner manufactures every product sold under the brand. Given the extremely broad product range observed in marketplaces, it is plausible that products are sourced from various manufacturers or suppliers and marketed under the SJLERST name. Public sources do not establish the existence of a single SJLERST-owned factory or manufacturing facility.

SJLERST’s distribution strategy offers significant insight into its business model. Rather than concentrating on a specialized product category, SJLERST products appear across numerous online marketplaces. For instance, ManoMano’s SJLERST brand page lists items covering interior equipment, vacuum accessories, car adapters, room lighting, and garden storage.4

Other marketplaces display similarly broad assortments, including automotive lighting, replacement mechanical parts, electrical equipment, lighting accessories, tools, computer accessories, consumer electronics, household products, gardening equipment, beauty equipment, and solar equipment. This breadth is characteristic of a generalist marketplace brand. SJLERST appears to focus less on building an iconic product category and more on supplying a large volume of relatively specialized products through online retail channels.

Home and lighting

Home lighting is one of SJLERST’s visible categories. Products sold under the name include rattan lampshades, metal lampshades, fabric lampshades, and other lighting accessories. Retailers such as Leroy Merlin list SJLERST lampshades designed for E14/E27 bulbs.22 This suggests participation in the affordable home decoration and lighting accessories segment.

Electronics

SJLERST products have appeared in consumer electronics categories. Examples found in marketplace databases include wireless computer mice, Bluetooth speakers, power supplies, keyboards and keycaps, thermostats, and various electronic accessories. A Korean retail listing, for example, identifies a wireless gaming mouse as sjlerst.5 Older product databases also record SJLERST Bluetooth speakers, confirming the brand’s use on consumer electronics.6

Smart-home products

The brand also appears in smart-home equipment. One SJLERST product is a Tuya Wi-Fi smart thermostat supporting programmable temperature control, voice-control integration, and the Smart Life ecosystem.7 This places SJLERST partly within the low-cost smart-home accessories market.

Automotive products

Automotive accessories form another significant category. Examples include USB and car power adapters, vehicle electrical accessories, replacement parts, automotive lighting, and LED tail lights. A ManoMano listing identifies SJLERST-branded tail lights for Volkswagen Golf 7/MK7.5 models featuring sequential indicators and a plug-and-play design.8 Listings on the platform also include vehicle-related adapters and electrical products.9

Tools and mechanical components

SJLERST appears in tools and replacement-parts categories with items such as carburetor replacement components, pneumatic cylinders, welding glasses, electrical components, water valves, and workshop accessories. Product listings identify SJLERST pneumatic cylinders intended for DIY, automotive, and model applications.15 Automatic-darkening welding glasses branded as SJLERST are also listed on ManoMano.21

Garden and outdoor equipment

The brand is represented in garden and outdoor products, including garden storage, solar-powered ventilation equipment, water pumps, pool accessories, and gardening components. A 2025–2026 marketplace record lists an SJLERST 15 W solar-panel fan and ventilation kit intended for greenhouses, attics, and poultry houses.10

SJLERST maintains a distinctly international online distribution footprint. Evidence of sales or listings can be found across marketplaces serving Europe, North America, Japan, South Korea, Southeast Asia, and other international markets. The brand appears on European platforms including ManoMano and Leroy Merlin, while other records indicate presence on Amazon-linked marketplaces and Asian e-commerce retailers.111720

Trademark registrations in both the European Union and Canada further indicate an intention to protect the brand internationally.12

Based on observed products and pricing, SJLERST generally targets the affordable-to-midrange online marketplace segment. The brand frequently competes on low or moderate price, broad availability, functional specifications, compatibility with existing equipment, convenience, and niche product availability. SJLERST-branded lampshades, welding glasses, automotive components, and household accessories often appear alongside numerous competing third-party products on marketplace sites.13

This positioning differs significantly from premium brands whose identity relies heavily on design, heritage, proprietary technology, or long-term customer loyalty.

Unlike conventional brands with clearly defined product philosophies such as “premium audio” or “professional tools,” SJLERST uses its trademark across many unrelated categories. The same name appears on lighting, electronics, automotive components, tools, household equipment, gardening products, and smart-home devices. This suggests that the SJLERST name functions primarily as a commercial brand identifier across an e-commerce product portfolio rather than as a narrowly defined lifestyle brand.

Reliable public information regarding SJLERST’s manufacturing infrastructure is limited. While some individual product listings identify sjlerst as the manufacturer, others provide different manufacturer or seller information. For example, a product record for a 12V water solenoid valve identifies “sjlerst” as the manufacturer and lists China as the country of origin.14

However, this should not automatically be interpreted as evidence that SJLERST owns a factory producing that particular product. Many marketplace brands work with third-party factories, OEM suppliers, or contract manufacturers. Therefore, SJLERST is best described as a China-associated consumer goods and e-commerce brand whose trademark is owned by Shenzhen Yibai Network Technology Co., Ltd., without public confirmation that all products are manufactured in a single company-owned facility.

Trademark databases show that Shenzhen Yibai Network Technology Co., Ltd. owns SJLERST alongside numerous other trademarks.15 The company appears to have developed a portfolio of separate brands, potentially allowing individual product lines to target different niches or marketplaces. This pattern is common in cross-border e-commerce, where companies operate multiple brands simultaneously rather than placing every product under one universal corporate name. Consequently, SJLERST is accurately described as one brand within a broader e-commerce brand portfolio.

SJLERST does not depend on a dedicated retail chain. Instead, products are distributed through marketplace-oriented channels. Documented examples include:

• ManoMano: Hardware, home improvement, automotive, and household products1623
• Leroy Merlin marketplaces: Lighting and home products22
• Amazon-associated listings: Various categories
• Asian online retailers: Regional e-commerce platforms1720
• Other international marketplace sellers: Including Cdiscount, Lazada, and Desertcart242526

This marketplace-centric distribution explains how SJLERST maintains a large assortment without the physical retail visibility typical of traditional brands.

SJLERST’s trademark history provides evidence of its international commercial strategy.

A separate UK trademark record also lists sjlerst under the same broader trademark portfolio.18

Several characteristics distinguish SJLERST from conventional consumer brands:

1. Extremely broad assortment: The brand is not restricted to one industry; ManoMano alone shows SJLERST products in numerous unrelated categories.19
2. Strong marketplace orientation: Most publicly visible evidence comes from online marketplaces rather than traditional brand stores.
3. International trademark protection: Trademark registrations in Europe and Canada demonstrate formal protection outside China.12
4. Chinese corporate association: The trademark owner is identified as Shenzhen Yibai Network Technology Co., Ltd., based in Shenzhen, China.12
5. Multi-brand strategy: SJLERST exists alongside numerous other trademarks owned by the same company.15

There is insufficient independent information to assign SJLERST a meaningful global reputation score comparable to established brands. Reviews are generally attached to individual products and sellers rather than a centralized SJLERST customer-review system.

Consumers evaluating a SJLERST product should assess the exact product specifications, seller reputation, warranty and return policies, relevant electrical or safety certifications, replacement part availability, and customer reviews for that particular model. This diligence is particularly important because the SJLERST name covers products ranging from simple household accessories to electrical, automotive, and mechanical equipment.

Based on available evidence, SJLERST should not currently be characterized as a major multinational manufacturer, a specialist electronics company, a dedicated automotive company, a luxury or lifestyle brand, a single-category home brand, or a company with a well-documented public corporate history. The evidence points instead toward a broad, marketplace-oriented consumer-products brand.
