### ⭐⭐⭐⭐⭐ Perfect for clinicals – Just don't forget batteries!
*by N***E on December 7, 2025*

As a nursing student, I needed a reliable penlight for my assessments, and these are perfect. The light is bright enough to check pupils without blinding the patient, and the pupil gauge printed on the side is incredibly helpful for a quick reference during neuro checks. Important Note: These do not come with batteries! Make sure you buy a pack of AAA batteries separately so you aren't stuck without them on your first day. Otherwise, they are sturdy, lightweight, and clip easily onto my scrubs. Pros: • Perfect brightness (not too dim, not too harsh). • Pupil gauge on the side is super useful for students. • Clips securely to pockets. Cons: • No batteries included (requires AAA). Fits in scrubs pocket, does not fall!! Button works great, doesn’t gets stuck
