Dimension comparison
Pricing
The Wagner Stern ultrasonic whitening Electric Toothbrush is priced at $9.95, making it significantly cheaper than the 7AM2M Electric Toothbrush, which costs $19.99. This means the Wagner Stern toothbrush is about 50% less expensive than its competitor. For budget-conscious consumers, this considerable price difference may be a decisive factor. However, the higher price of the 7AM2M toothbrush reflects its enhanced features and capabilities, which may justify the additional expense for some users.
Cleaning Power
When it comes to cleaning power, the 7AM2M Electric Toothbrush boasts a powerful motor that produces 40,000 vibrations per minute, effectively removing up to 125% more plaque compared to manual toothbrushes. In contrast, the Wagner Stern toothbrush features an impressive 48,000 sonic vibrations per minute and claims to remove up to 10 times more plaque than a manual toothbrush. While both toothbrushes offer significant plaque removal, the Wagner Stern's higher vibration count may appeal to those seeking a more aggressive cleaning experience.
Modes of Operation
The 7AM2M Electric Toothbrush offers five customizable modes: Clean, White, Polish, Milder, and Sensitive. This variety caters to different oral care needs, making it suitable for all family members. On the other hand, the Wagner Stern toothbrush also provides six modes: Sensitive, Cleaning, Deep Cleaning, Massage, Whiten, and Polish. This additional mode gives the Wagner Stern a slight edge in versatility, allowing users to choose a setting that best fits their specific dental care requirements.
Brush Heads
In terms of brush heads, the 7AM2M Electric Toothbrush comes with six replacement heads, providing a full 18 months of care. This ensures that users won’t need to purchase additional heads for quite some time. Conversely, the Wagner Stern toothbrush includes eight charcoal black brush heads. Although the 7AM2M provides fewer heads, the quality and design of each may be more tailored for dental health. Both options present good value, but those who prioritize quantity may lean towards the Wagner Stern.
Battery Life
The battery life of the 7AM2M Electric Toothbrush is rated for an incredible four months on a single charge, which is exceptionally long compared to many electric toothbrushes. In contrast, the Wagner Stern toothbrush offers a battery life of about two months. This difference in battery longevity means that users of the 7AM2M can go longer between charges, making it a more convenient option for those who travel frequently or dislike the hassle of frequent recharging.
Smart Features
Smart features are crucial for modern electric toothbrushes, and both the 7AM2M and Wagner Stern models include timers to help users brush effectively. The 7AM2M has a built-in smart timer that notifies users every 30 seconds to switch quadrants, ensuring a thorough two-minute brushing session. The Wagner Stern toothbrush also includes a smart timer, promoting the dentist-recommended brushing duration. While both toothbrushes facilitate a good brushing routine, the more detailed quadrant timing of the 7AM2M may offer an advantage for users looking to maintain a consistent oral care regimen.
User Experience and Design
User experience is enhanced by the design of each toothbrush. The 7AM2M features a unique "W" shape that conforms to the contours of the teeth, which helps in reaching difficult areas for a complete clean. The gentle, gum-protecting bristles with fade-to-replace indicators add to its thoughtful design. Conversely, the Wagner Stern toothbrush is designed with high-quality super soft charcoal bristles aimed at providing a deep clean while being gentle on gums. While both designs focus on user comfort and effectiveness, the 7AM2M’s ergonomic design might be more appealing for those with sensitive gums.
Which should you buy?
Choosing between the 7AM2M Electric Toothbrush and the Wagner Stern ultrasonic whitening Electric Toothbrush largely depends on your specific needs and budget. If you are looking for a budget-friendly option with good cleaning power and additional brush heads, the Wagner Stern may be the better choice at $9.95. However, for those willing to invest more for enhanced features such as a longer battery life, customizable modes, and a thoughtful design, the 7AM2M at $19.99 would be a worthwhile purchase. Ultimately, both toothbrushes offer significant benefits, making them solid choices in the electric toothbrush market.
