These are very good opera glasses. The choice was to have the ones I bought, with a necklace so that I don't have to keep them in my hands or on my lap when not in use, or another pair that came with a light but no necklace. I wish there had been a model that had both.
Pros: work well in dark theater, fits easily in purse or pocket
Cons: no light
