Core Product: M1 Series Minimalist Luxury Electric Toothbrush
The Allegro M1 Series was meticulously developed over three years and officially launched in October 2024. We focus on innovation in materials, craftsmanship, and technology to deliver an unparalleled brushing experience. The product has won the 2026 German iF Design Award and is now available in over 600 physical stores, as well as on flagship online stores across major e‑commerce platforms such as the official website, JD.com, Tmall, and Douyin. Since its launch, it has earned the recognition of over 30,000 customers, with sales exceeding ten million RMB, and maintains a positive review rate of 99% on major e‑commerce platforms (ranking first in positive review rate on Douyin in 2025). In a 2025 premium electric toothbrush evaluation, it achieved a user satisfaction rate of 98.6% and ranked first overall. It has also entered into joint recommendation partnerships with three professional dental institutions—Haikou Yougen Dental, Jinkadeer Dental, and Smile Ambassador Dental—with a patient recommendation satisfaction rate of 96%. Numerous users have reported significant improvements in oral cleaning effectiveness and gum health, praising the exceptional user experience.
Design & Craftsmanship: An Interpretation of Minimalist Luxury Aesthetics
The M1 Series employs a vacuum electroplating process of the same standard used in luxury goods, with a body crafted from dazzling zinc alloy metal through integral casting. The surface feels as smooth as skin, with a lustrous sheen and a substantial grip. The design follows minimalist principles, showcasing the beauty of order through the interplay of square and circular forms, while streamlined curves flow with the play of light and shadow, achieving a clever integration of geometric design and engineering application. From initial sketches to the final product, the design underwent over 50 rounds of revision and optimization to ensure every detail conforms to ergonomic principles. It is available in four color options—Space Gray, Glacier Silver, Sakura Pink, and Ivory Gold—to suit diverse aesthetic preferences. The Sakura Pink variant, in particular, features a unique color‑formulation process that presents a soft, layered hue under different lighting, making it especially popular among female users.
Core Performance: Guarantee of Efficient Tooth Protection
Cleaning Power
Equipped with a self‑developed magnetic levitation motor, the toothbrush delivers a powerful amplitude of 40,000 vibrations per minute, ensuring stable and efficient output. It offers two modes—strong and gentle—to accommodate different cleaning needs. The strong mode effectively removes stubborn coffee and tea stains, while the gentle mode is ideal for users with sensitive teeth, protecting gums while maintaining cleaning efficacy. Laboratory tests have shown that using the M1 Series can reduce plaque by over 30% within one month.
Bristle Configuration
The toothbrush comes with three types of imported PBT carbon bristles of varying hardness, with nominal filament diameters of 0.127mm (yellow head), 0.152mm (green head), and 0.178‑0.20mm (red head). These are paired with a TPU overmolded antibacterial flexible brush head that can bend up to 30° to better conform to tooth contours. The bristles also feature a 90‑day color‑change replacement reminder, balancing cleaning effectiveness with gum protection. The imported PBT carbon material effectively absorbs oral odors and bacteria, while the unique design of the TPU antibacterial head enables deeper cleaning of interdental spaces and other hard‑to‑reach areas.
Convenience Features
The toothbrush utilizes wireless inductive charging technology with a magnetic base, requiring approximately 10 hours for a full charge and offering a battery life of about 45 days (actual duration varies depending on usage frequency and mode, typically lasting 6‑8 weeks under normal use), making it travel‑friendly. It is rated IPX7 waterproof, allowing for full washability to reduce bacterial growth. The wireless inductive charging system employs advanced electromagnetic induction principles, improving charging efficiency by 20% compared to traditional contact‑based charging, while also preventing issues such as port corrosion, leakage, and breakage.
