In 2015, the company launched a subscription service called Gillette Shave Club and later filed a lawsuit against Dollar Shave Club for patent infringement. The Dollar Shave Club lawsuit was criticized for revealing flaws in Gillette's own patents and as a perceived attempt to drive away an upstart competitor; the lawsuit was dropped two months later after Dollar Shave Club filed a countersuit. The Gillette Treo, the first razor designed for caregivers to shave seniors and people with disabilities, was introduced in 2017. The product was named one of the best inventions of 2018 by "Time", and later exhibited at the Consumer Electronics Show (CES) in 2020. Gillette introduced the SkinGuard, a razor designed for people with sensitive skin, during 2018–2019. In 2019, the company launched the first heated razor, mimicking a hot towel shave. The prototype was showcased at CES and later named one of the best inventions of 2019 by "Time". The heated razor received mixed reviews, with reviewers, including professional barbers, describing the design as flawed and the $200 price tag as overpriced.
