Jeemiter Cobalt Blue LED Professional Medical Penlight PenLite with Metal Clip for Ophthalmologists Doctors Nurses and Eye Examiner

Light is impressively bright and blue, and exceeds expectations. Pen is structurally flawed as others have described. Lightbulb is too small/short and jiggles inside the screw-in cap, causing poor battery contact and flickering. This was easily fixed by gluing the bulb to the cap. A total game-changer for examining infants and the elderly.

This is a piece of crap it does not work at all this is the second one I bought hoping it would work NOPE Do NOT buy this product

Works as it should.

I am a physician and bought this penlight specifically because it is listed as having cobalt blue LED. The penlight as depicted in the photo is a bright white LED. The product also had no instructions on how to install the batteries. Overall, the penlight looks very cheaply made. Looks like other buyers have had quality issues also. I am returning this as it is not what was described.

A bit disappointing especially noting previous 5 star reviews. Difficult to turn on and off. Light flickers. Blue filter is loose and seems at risk of falling out. Price is good and bright blue light excellent. Battery life is an estimate but should be good. Durability also an estimate but given that the product already has issues I do not predict a long life.

Very handy and replaces the need for the black light for eye stains.

This is a great inexpensive alternative to the pricey Welch Allyn penlites. Work just as well. I would buy again.

This product does not work (no light produced at all). I ordered a second one hoping it was a manufacturing defect, but the second one was also nonfunctional. Very disappointing!
