So this neck light is so neat and easy to use. it is rechargeable so not changing batteries just plug it and let it charge. it has three setting so you can choose which one works best for your needs. it fits around many different size necks and the ends can be moved for the prefect poistion. I love using this light to read at night so I can still read and not wake up my family. https://www.amazon.com/…/B07…/ref=oh_aui_detailpage_o01_s00… #dfytg
