While I had used many of Welch Allyn products previously and found them to be of excellent quality, the diagnostic set I purchased has fallen short.
I first noted that the light would not come on when the handle was tightened, and I realized the metal contact in the handle was misaligned by 20 degrees or so. I was able to fix this myself by forcing the contact into its intended position to get the light to reliably turn on.
The other issue is that the cone of light from the otoscope is not a perfect circle, but the light is missing for around 30-40 degrees of arc. This does not impact much on examination, but is disappointing nonetheless.
Otherwise, the LED globe is highly recommended for its benefits of lifespan, and does not differ significantly in use from halogen models, with more brightness than you will ever need. The stand is also great and charging works flawlessly.
Overall, a great product, hampered by some manufacturing faults which missed quality assurance checks.
