I bought the device from another vendor. I needed something usable that would comfortably magnify things. This device was presented to me and recommended to me in our 9mm - N-Bahn forum. At the price of around 40€ you can't go wrong - I thought and wasn't disappointed either. I always leave the device set up and have a suitable bag, which I pull over as dust protection. Regarding the magnification, I would say: 10x is possible! ---> 100 times maybe too! ---> In any case, I laughed 1000 times trying it out!+++ The device is set up quickly and easily and is ready for use.+++ THE DEVICE DELIVERS EXCELLENT RESULTS!!!+++ A fairly large 3.6 V Li The Ion battery is replaceable - so the device can also be operated without a cable.+++ Surprisingly good workmanship. +++ The display has a sufficiently good resolution and is pleasantly bright.+++ The lighting is continuously adjustable+++ There is an extensive function menu with various settings.+++ The device can be equipped with a mini SD card.+++ Photos and films can be made with an SD card.+- Unfortunately, the instructions are only in English. But very extensive.+- The device was neatly packed in a neat box.+- A USB cable is included - A charger - or power supply unit is not!- The technical information on the magnification power cannot be taken very seriously.- The menu operation and the Buttons on the display take a lot of getting used to and are fiddly. For the price and the results, I am completely satisfied with the device! VERY CLEAR BUY RECOMMENDATION!!! +++ The lighting is continuously adjustable +++ A comprehensive function menu with various settings is available. +++ The device can be equipped with a mini SD card. +++ Photos and films can be made with an SD card. + - The instructions are included unfortunately only in English. But very extensive.+- The device was neatly packed in a neat box.+- A USB cable is included - A charger - or power supply unit is not!- The technical information on the magnification power cannot be taken very seriously.- The menu operation and the Buttons on the display take a lot of getting used to and are fiddly. For the price and the results, I am completely satisfied with the device!
