I have owned the expensive W.A. Penlight, the copy cat ADC version, and numerous others. This particular version of the MDF blows all other penlights away. Other MDF penlights I have not been happy with however this latest version they hit a home run. Pros: 1) The light is a warm white which is best for getting true tissue color as the insanely bright LED bulbs that some penlights come with distort colors. Perfect for checking pupils as well, not blinding to patient. 2) Nice weight to it and the outside has a slight "grippy" texture to it. 3) There is a pupil gauge and ruler. 4) Light easily clicks on and stays on until clicked again. 5) Sturdy construction - dropped a couple times on hard flooring and still working. 6) Inexpensive for the quality you receive in this product. Cons: NONE; Best medical penlight I have owned and easily beats the top penlight that ADC sells....AND this beats the Welsch Allen penlight. MDF did their homework on this penlight. Buy this penlight and you will forget all the ones you have used in the past that you have been dissatisfied with for one reason or another. UPDATE: After close to two years of using this penlight I can report that my original review was an accurate one even after long-term almost daily use. This MDF penlight is still working flawlessly in function and looks. All I have done is change the battery a couple times. I can state with confidence even after long-term use that MDF really did their homework on this instrument. Also, still in opinion that this is superior to the W.A. Penlight and its ADC copy cat penlight. Was so happy I have bought 2 more of these penlights so I could stock up on them in case they ever discontinued this amazing penlight. Review: MDF makes excellent products - I trust the brand MDF. I have stethoscopes, blood pressure cuffs, and now a professional medical illuminator aka small pen light for looking in patients eyes, ears, mouth, and throat. This pen light is excellent in every way. It's strong and holds up to dropping because it's solid metal. It's got a high quality on/off button on the top of the pen light. Just one click on and off only. The amber LED light bulb will last forever. It's not too bright for a patients eyes unlike some LED pen lights I've had. The tip is chrome and can easily be wiped off and sanitized in between patients. The tip unscrews with fine threads which is how you change the AAA batteries. In general, batteries can swell up and even leak due to an increase in gases with in the battery. This is why I'm using lithium ion rechargeable batteries. Longer life and less likely to expand and leak like alkaline batteries ie. energizer and duracell. The barrel of the pen light has a white, rubber coating which has not worn off or peeled like other rubber coated items I've had in the past. Every thing including the clip is metal, durable, long lasting, and a bit on the heavy side (82.2 grams with batteries). The barrel has mm pupil sizes and a small ruler both of which are quite useful. There's nothing I would change about this pen light except maybe make a black version since it would better match my outfits. ## Features - TRUSTED by Medical Providers - Doctors, Nurses, Students, Home Health since 1971 | 1-Year Warranty | Latex-Free - Features a warm LED light for safe eye examination - DURABLE and heavy duty copper construction - NON-SLIP surface with pupil gauge reference and ruler - ON/OFF button at the bottom of the penlight to operate with ease.
