To always have it in your pocket or in the car, very good.
For continuous use at home or in the office, not so much.

Very sturdy and practical case, the best when it comes to portability

The arms are short and do not grip at all behind the ears, so the glasses fall off as soon as I bend down. I threw them away.

The lenses are clear and very lightweight. They are good to have as a backup for emergencies, because they really fit everywhere. However, be careful. They are extremely small. When you wear them, you can see the outline of the frame in front of you. What they write in the description, 'comfortable use and fit for almost all faces,' is not true. They are only suitable for very small heads. For me, the arms barely reach my ears. As soon as I tilt my head down, they fall off. Also, from the contents of the package, at least for me, only the case arrived. The other two items were missing, which I didn't care about anyway. I am attaching photos for comparison with a second pair I bought, which are like the glasses we all know.

Clear lenses, lightweight and smart case so they don't break in your pocket. Ideal for travel, and to keep in your coat pocket without bothering you
