Review on 📽️ DHAW 3800LM Full HD HDMI Video Projector for Laptop Business PowerPoint Presentation and Home Theater (with PPT Clicker) by Michael Colley

I needed a PowerPoint projector for a small group. The picture was bright and clear. The room wasn't completely dark. The LASER Presenter was the only part I had trouble with. It looks like it's draining the batteries. I put in a new battery, practiced the program a few times. worked fine The next day he was dead. Again put in a new battery. worked fine The next day he was dead again. I installed a new battery. worked fine This time I took out the battery when I was done and put it back in when I started the program. worked fine I don't understand how it drains the batteries when not in use. I also removed the part that connects to the laptop in between. But as a pointer and clicker to switch slides, it worked just fine.
