I bought a Country V portable laser, which was pre-sold. The price was reasonable, as pre-sold items can't be sold at excessively high prices. The laser frequency marking on the handle is easy to distinguish. However, I didn't use a lanyard and it broke when I dropped it. So I bought another one. This one's laser frequency marking wasn't visible at first, but after contacting the manufacturer, they confirmed that it was there. It just has finer markings and only in one direction, while the pre-sold version had markings in three directions. In reality, some accessories are essential for using the product properly, but Country V's portable laser is still quite efficient!
