The endoscopic camera comes in a really solid and comfortable case. After opening the case, you will see three parts of an endoscope: USB (or HDMI) wire, optical coupler, and the camera itself. The camera has a cylindrical shape, just as seen in the pictures; it is very ergonomic and tiny (much more comfortable than those I had before). The optical coupler looks really durable, composed fully of solid metal (the only plastic part is the optical aperture cover on the back). The frontal aperture is covered with a tightly placed metal cap. Fixation of both covers and endoscopes is really fast; there is no way it falls off by itself or unintentionally. The USB wire is spiral and pretty long, it looks reliable, and I think it will last for a long time.
Picture quality and other features: This camera provides a really nice, smooth picture. White balance works automatically (I think it depends on the software). It works perfectly fine with the camera app on Windows and with many other webcam software that I tried. Please be sure which optical coupler you need (because it depends greatly on the endoscopes that you are using); in case you are not sure or don't know, ask the support team. They are really nice and kind. Also, they respond really quickly (that was a pleasant surprise for me). In general, I am extremely satisfied with both the product and the support team, and yes, I would recommend it to a friend.
