Quick Verdict
Choose Air 4 if your hair and skin fit Ulike’s guidance and you want manual energy control with contact cooling at a low price. Its five-week start asks for three sessions a week, then two, plus shaving, goggles and a first-use skin test. Buy it for that feature-and-price combination, not a one-treatment finish.

What we know
Why it matters
The cooled sapphire window is the Air 4's headline design feature — documented by Ulike, not independently measured, and comfort will vary from person to person.
What this means for you
Ulike states the sapphire window stays near 64.4°F during use, which is designed to take the edge off each flash on sensitive areas. Treat it as a comfort aid that can make a three-times-a-week schedule easier to keep, not a promise of painless sessions.
