It is the second one I buy. In general, they work fine, I did not encounter any problem. It has a sensor that is closed during the day and turns on until early in the morning when it turns off again (auto function). You can also open and close it with the remote control whenever you need it. The cable is quite long, which is convenient for placement. From the dealership I called to ask if there is any kind of extension cord if I want to raise the panel higher, they told me that it does not have one and that it is the latest model with such a long cable, so future buyers should know that. Also, I still haven't figured out how the controller works and which indicator is activated. I have found a trick. If you remove the panel from the lamp (and it has a battery), then it turns on, so I press off and reconnect it and then press auto, and it works with the sensor. So far, it has been working without any problems for a year and a half. In the snow of Attica in January 2022, I simply covered the panel with nylon, the funny thing was that the projector was working fine at night.

I was thinking for a while about buying the projector for testing, because I wanted to light up a 40 sqm storage room that has no electricity with 3-4 of these. I thought 25W * 4 would be enough brightness with 2800 lumens each. Also, since the specifications do not mention the battery capacity anywhere, I contacted Bormann and they replied that it is 12Ah. When it arrived, unfortunately, I was disappointed. I expected it to be much stronger. I would say it is equivalent in brightness to a 5-watt bulb at most. And because the beam angle is smaller than a regular bulb, the lighting is worse. Nevertheless, its battery is satisfactory. I tested it for up to 6 hours without the brightness dropping. The instructions inside mention a green light when there is a full charge, but there is none on the projector. There is only a red one that blinks when charging and receiving light. The remote control is not the best construction. And unfortunately, there is no other way to operate the projector if it breaks. As for waterproofing, I wouldn't place it somewhere that receives direct water. Perhaps better under some shelter. Its cable is about 3 meters long. Also, the projector can be disconnected from the panel and taken wherever you want, as long as it is charged. I believe that for lighting outdoor spaces to see where you are going, it is okay. For indoor lighting at these watts, I wouldn't recommend it. Maybe only for emergency situations. I hope I helped.
