Most Lasers, Longest Warranty, Filed Under Neither

The MD DUO is Capillus's largest cap: 320 lasers, 280 at 650 nm and 40 at 808 nm, each 5 mW and a stated Class 3R, in an elongated dome that Capillus says reaches toward the back of the head and the top of the sideburns. It runs an auto-timed 6-minute daily session from a rechargeable battery pack, and it is the only Capillus cap with a 5-year warranty, stated on its product page though Capillus's warranty table has no MD DUO line. Capillus sells it as FDA-cleared and the registration lists it under K162994 and K163170, but neither describes a 320-laser cap or any near-infrared laser, so it scores 2 on verification. No output measurement has been published. At $3,699 it is the most expensive Capillus cap, $1,000 more than the Spectrum, which has the same 40 near-infrared lasers and 8 fewer red ones, while a physician dealer lists it at $3,200. Every social pool on this page draws on sibling caps, because no owner review or rated retail listing covers the MD DUO yet.

The Capillus MD DUO is a cordless laser cap with 320 diodes, 280 at 650 nm and 40 at 808 nm, which Capillus states run at 5 mW each as Class 3R laser products. Its elongated dome is designed to extend toward the back of the head and the top of the sideburns, and an auto-timed session runs 6 minutes a day from a rechargeable battery pack with an AC adapter. Capillus covers it for 5 years; it was earlier registered under the name Spectrum MD.

Capillus holds 4.4 from 1,626 Trustpilot reviews on capillus.com (TrustScore shown as 4.5), split 70 percent five-star against 12 percent one-star, with 206 posted in the last 12 months; the company invites customers to review, has kept a claimed, paid profile since February 2016, and replies to 84 percent of negative reviews, typically within two weeks. Most recent five-star entries are short invited notes praising named support staff, while the 2025-2026 one-star reviews center on discontinued 4.6-volt battery packs for older caps, a one-year battery warranty against the three-year cap warranty, slow refunds and email-only support. BBB lists the company as Curallux LLC (Doral, FL) with a D- grade, no accreditation, 11 complaints in three years (the grade cites 12 left unanswered) and a notice that the company will not resolve disputes through BBB; the complaint themes are the 25 percent fee deducted from satisfaction-guarantee returns, refunds not issued once a cap was returned, repair and warranty delays, and unanswered calls. SmartCustomer (formerly Sitejabber) lists capillus.com with 0 reviews and flags it as not collecting reviews, ConsumerAffairs carries no Capillus page, and no other Capillus domain has a Trustpilot profile. capillus.com shows its own Stamped.io star widget (4.8 from 63 on the PRO page, with an AI-generated review summary) and advertises "4.5 from 2,475 reviews on Amazon", figures no pool counts; the Amazon cap listings total about 670 ratings at 3.1 to 3.8 stars.
