Kala Therapy Hat
Read the full summary
- Hat review: Marco Gentile's, which carries Kala code MARCOGENTILE, relays testers' remarks and describes no sessions of his own, so it is not a pool
- Face mask: Light Therapy Insiders (Alex Fergus), a market-wide tester with a Kala affiliate link, scored it 63 of 100 in July 2025 on a gifted unit, marking it down for coverage gaps, the cord and the return terms of the time
- Restore Wrap: also provided free, found well built but low in output (September 2026)
- Scope: neither is a hair cap, so this reading sits a point lower
Bon Charge Red Light Cap
Read the full summary
- Scope: no hands-on review of the cap is published; magazine pieces list it without a period of use
- Across the range: monetised editorial testers are mostly positive on build, comfort and ease of use and criticise the price
- mindbodygreen: publishes with Bon Charge's code; covered six devices including the Mini and the wand
- Wareable: a market-wide affiliate; covered the mask and the wand
- Light Therapy Insiders: a market-wide tester holding Bon Charge code ALEX; ranked the first-generation Max last of 17 panels on output in 2024
- Weighting: none of that coverage is of a cap, so this reading sits a point lower
