Which is better, this Willing hand-held endoscope or Olympus?

From the point of view I have used, it must be Olympus ~ After all, Olympus has a hundred years of history, and its quality and reputation are impeccable. IPLEX G Lite handheld endoscope, in particular, as one of the representative products of Olympus, is well-known in the industry. IPLEX G Lite is not only compact and durable in design, but also has powerful imaging capability, which can provide clear and accurate detection results in various application scenarios. IPLEX G Lite is portable and can be taken to any place where testing is needed at any time. Moreover, Olympus's products are characterized by simple operation, rapid mastery and greatly improved work efficiency, so you must look at Olympus's equipment in pursuit of ease of use and efficiency ~
