I'm repurposing these and using them for a dog game that I'm building. I was looking for large buttons (momentary switches) to interface to my microcontroller (atTiny2313), but these were a bonus. All I really needed was the switch, but with the LEDS (which I was going to light up a different way) and with the sounds, this is great!I opened up the button and all 4 are actually identical except for the LED color (as well as the plastic button color). Each of these buttons plays all 4 sounds, it just depends on which pin is jumped on the board. The board is large enough where you can tap into the button (+ voltage), turn on the lights, and trigger the sounds.While this device works on 3V battery, I was able to successfully use it on 5V as well. I did put a small resistor inline to bump that down a bit just in case I was near the limits, so I'm at about 4.5 and everything looks normal. While the LEDs do have resistors on the board, they are of a low value (~50 ohm depending on the color), as it's expecting 3V. So on my trigger line I added a couple hundred more ohms.I know this review is outside the scope of just about anybody buying these, but in case you're a DIYer, these would work great for any microcontroller (e.g. arduino, raspberry pi, ATMEL etc).I'll get a video of what it will do once I'm done.

I bought these to use in my preschool class and they were a hit. Anytime I had group work and brought the buzzers out, my students were ecstatic. The sounds and light made review games fun for them! Definitely a MUST HAVE for teachers!!

I got this for a game show night my Search & Rescue group had. We had previously used a collection of bells and ringers we had gotten at thrift stores. These are soooo much better! The lights really help to know who buzzed in first and each sound is distinct. There is no volume contorl and that might have been nice. I've only used them once so am not sure if durability will be an issue. They have batteries so that shouldn't be an issue.

This item has been used so many time at our family events. The unique sounds are helpful when trying to decipher who buzzed in first or not. I wish they were a little louder but they are loud enough for playing.

Sound is loud and not able to adjust BUT these are intended to be used on a flat surface which would muffle/lessen the volume somewhat. They still are crisp and easy to hear. My kids love the different sounds! I have 3 kids and I plan to use these as buzzers for homeschool games and just fun activities. They will each get their own designated buzzer and there's one that sounds like a nice that means you got something wrong so maybe I'll keep that one for myself. So fun!!! I got these used like new and they were in perfect condition. They do require batteries so keep that in mind, but there is a screw to keep the battery compartment closed.

My son with special needs loves the funny sounds and lights when he hits them!

These buzzers were such a big hit! I got them for a game my Sunday School class played. Even the shy kids decided they wanted a turn so they could hit the buzzer. The buzzer sound wasn't too loud to be annoying for the adults. The buzzers seem durable but time will tell.

This product was bought for a game we used at work for team building. The price worked as intended. Nothing bad to say
