PIR Motion Sensor Activated Sound Player Speaker with USB Cable, Download Your own MP3 Audio Files to Play Speech, Music or Sound Effects (White)

Not sure why the negative reviews. This was SUPER easy to use, some complained about the instructions? It's so basic the instructions that come with it are perfect! And, you DO NOT need a computer! I EASILY deleted the files on it and uploaded my own from my Pixel 9 pro! Simply get an adapter. When you plug it in it shows up as a USB storage device. Open it, delete the files. Save whatever MP3 you want to upload to your files folder and simply transfer it! It took me maybe two minutes from opening the box and having my own sounds uploaded! And it sounds just fine for my use. Just an EXCELLENT PRODUCT!

I used this to remind my family to plug the electric car charger in when they come into the garage. It fixed the problem of forgetting to charge the car.Great product but you need to use a windows pc to format it and place your sound files on the device. If you do this you will not have any issues with the device becoming corrupt or having the old files still remaining on the device. The operation is also very simple. You just need to follow the instructions to set it up.Great sound and features....The price is also very reasonable. Will buy it again.

Easy to use. The motion sensor is accurate and has a wide angle. I had to put some tape on it to narrow it a bit for my usage.Once you plug it into a computer via USB, you'll see all the preloaded sound files. They are MP3 format. You can simply add your own sound files and/or remove the ones you don't want.The little white buttons are then used to rotate through the sound files to the one you want.The mount seems sturdy. The bottom is flat enough you can just stand it up on its own. I used a bit of double sided tape to make it a bit more sturdy.The only con is you basically have 2 volumes: Loud and Very Loud. A volume knob would be nice.So far, it's working to keep the animals away, so I'm very happy.

I used these for a public art piece that needed motion-sensor sound and they worked perfectly. It was super easy to load music onto each one, and the motion sensor was exactly as sensitive as I needed it to be. They were much louder than I expected them to be, which was a plus since my installation was outside. I wrapped mine in adhesive vinyl to match the art, and also hopefully protect them outside, and, amazingly, that worked. They were outside for 6 months and worked to the very end. And the batteries never died! Great price, great product. Would definitely use again for public art.

Unit is aok for the price but I think it could have included an active micro SD slot, and possibly avariable volume selection (only has 2 choices, loud and louder)
