The SURI 2.0 meets
the Aquasonic Black Series
Premium aluminum build with the longest battery life in its class. We tested it head-to-head against the Aquasonic Black Series ($39.95) across 6 key dimensions.
Aquasonic Black Series
“Eight brush heads and a travel case for under forty dollars”
Head-to-Head Breakdown
Strengths & Weaknesses
SURI 2.0
- Premium aluminum handle weighs just 77g and feels built to last for years (Electric Teeth)
- 38-day battery life is the longest in our lineup, tested by Electric Teeth's manual drain method
- Slim USB-C charging travel case with built-in UV-C sanitizer keeps brush heads clean on the road
- B-Corp certified with plant-based brush heads and free mail-in recycling scheme
- Magnetic wall mount keeps the brush off your counter and away from bathroom splashes
- Only 2 brushing modes where competitors offer 4-5 at this price (Electric Teeth)
- Pressure sensor requires 10-20% more force to trigger than rival brushes (Electric Teeth)
- No pause function: pressing the power button resets the 2-minute timer entirely
Aquasonic Black Series
- Unbeatable bundle: 8 DuPont brush heads plus a travel case for around $40, enough heads for 2+ years (Electric Teeth, Product Guide)
- 40,000 VPM motor with ADA seal of approval for plaque removal (Product Guide)
- 30-day lithium-ion battery life is roughly double what entry-level Oral-B brushes offer (Electric Teeth)
- Four cleaning modes (Clean, Soft, Whiten, Massage) with backlit labels on the handle
- No pressure sensor at all, so nothing stops you from brushing too hard on your gums (Electric Teeth)
- Handle materials feel noticeably cheap compared to base models from Philips or Oral-B (Electric Teeth)
- Quality control is inconsistent: reports of handles failing and bristles shedding from brush heads over time (Electric Teeth)
The Verdict
Our Bottom Line
The SURI 2.0 wins because it solved the two biggest annoyances in electric toothbrushes: flimsy plastic handles that degrade in a wet bathroom, and batteries that die mid-trip. Electric Teeth, the channel that has spent a decade testing hundreds of toothbrush models, gave it their strongest editorial recommendation. Their plaque disclosing tests (using purple dye to reveal missed spots) showed cleaning performance on par with Philips and Oral-B brushes that cost twice as much.

- Willing to spend $135 for a brush that will last years with repairable aluminum construction
- Travels frequently and wants a slim USB-C charging case instead of a bulky charging stand
- Values sustainability: plant-based brush heads with free mail-in recycling
- Prefers a minimalist design with no app required for core functionality
- Wants the longest battery life available (38 days) to avoid packing chargers
Aquasonic Black Series
The Aquasonic Black Series wins the value pick by asking one simple question: how much should a first electric toothbrush cost to own for two years? At $40 (frequently on sale for $30), it ships with 8 DuPont brush heads and a travel case. Electric Teeth calculated that those 8 heads last over two years of use, which means your total cost of ownership is about $40. A Philips Sonicare 4100 at $50 ships with one head and needs replacements at $8-10 each every three months.
- First-time electric toothbrush buyer on a tight budget
- Wants to avoid buying replacement heads for 2+ years (8 heads included)
- Already has good brushing technique and does not need a pressure sensor
- Needs a travel case included out of the box without paying extra
- Prioritizes features-per-dollar over build quality and long-term durability
