Customer photo review of High-Lighter

I love it!! Easy to use, my only suggestion is to make sure to turn on /off after use to avoid draining the battery and burning thru your cart more than necessary.💗💗💗

Rachel S. 5/5 April 18, 2026

Very nice, highlighter size and looks just like one!

Stephen J. 5/5 Verified July 22, 2026

Such a fun and convenient thing to use! And it’s cute! love every part of these!

Jessica D. 5/5 Verified July 21, 2026

it’s as discreet as you want it to be, you just have to make sure your cart isn’t clogged bc it’s hard to unclog from taking a hit off the top. Despite that it’s still 10/10; wildly affordable, great build quality, powerful battery, convenient voltage settings, easy cleaning, and it’s a vibe lwk idk.
