We've needed a good microscope for a long time, but one that transmits images very clearly. Because I make jewelry every once in a while and these are real handcrafted pieces that require a lot of accuracy. We brought a few microscopes with us and are always very negatively surprised by the poor quality. You can see a lot - no question, but the picture is blurry, which is important to me, especially when I want to do hand engraving or connect 2-3 wires of different colors in a certain order. So we bought a microscope and needed it the next day until we got this one. First, it's modern and the HDMI port in particular is pretty cool - allowing me to stream images straight to the TV. Second, although it looks complicated at first glance, it turns out to be easy to use, but only if you already have some experience with it. Because from scratch you need some time to use it. The battery is ok, lasts longer, but it doesn't matter anyway because I can't stand to work longer - my eyes hurt. As a result, I find the battery life on this microscope to be a bit shorter than on previous devices, which I personally am absolutely fine with. Well, for hobbyists like me, this device is a big help. I can now keep everything to a minimum without maxing out the overall lighting in the room. That alone saved me a lot of energy and reduced my costs. Very satisfied. Clear 5 stars. Also clear purchase advice.
