1. Fair price for a solid product: bulb, cord, switch, and USB plug seem to be well constructed; if time reveals something not presently apparent, I’ll be back.
2. Convenient, sturdy metal hanging *hook*: hangs the bulb without the fuss threading something through a hole.
3. Soft, warm-light ambience: yellow tones complement human beings and are more restful for the brain.
The cord and switch are conveniently proportioned, too. To help you anticipate whether the lengths will work for your purposes:
Top of switch to bulb = 23.6″ (60cm)
Bottom of switch to top of USB plug = 36.5″ (92cm)
Switch is approx. 2.4″ long (6cm)
