Question about Atomos Shinobi II

I had ordered the Shinobi II with great anticipation - a dream for every videographer, I thought. But the euphoria quickly gave way to bitter disappointment. When I unpacked the monitor and tried to connect it, I realised in one fell swoop that this product is simply useless without a large number of accessories that are not included. It doesn't even switch on! After my investment of a whopping 327 francs, I had no choice but to open the shop again and dig deeper into my pocket to buy at least the essentials. After some research, another 144 francs were added on top - for accessories that, in my opinion, should have been included with a product in this price range. I would like to warn future buyers: the Shinobi II offers next to nothing in the basic configuration. If you plan to order it, plan a decent budget for additional purchases right from the start - and a lot of patience. @Atomos - such an experience is simply disappointing.
