    It's quite a nifty little set up. You need to set it up all yourself (because it is a kit). Figuring it out took a little longer because I needed to follow the pictures on the site (the instructions are in Mandarin so if you can't read it, it's useless). The photos for display on the listing gives a better idea of how the connections add up. I bought two sets, they both work really well. Things to note: 1. The photoresistor is very sensitive. If you don't tape over it when connecting to test and see if the kit works, you'll think it's not working because any light in the room will change the frequency of the buzzer, and it won't buzz. It needs to be fully dark to realise it is working just fine. 2. Remember to remove the sticker off the buzzer otherwise it will not be as loud as it should. 3. I literally had to cut off the plastic green walls and melt down the corners because it was so SHARP and I definitely hurt myself while trying to assemble the circuit before doing this. 4. The resistor provided is pretty awful. I have no experience with DIY circuits, so I had to figure out which of the 2 out of 3 legs of the resistor I needed to connect. You also need to twist them so they fit into the screw plates, which is not the easiest and I kept thinking I might accidentally break the legs off. 5. Screwing down the plates to solidify the connections needs to be done VERY STRONGLY. Because of the difference in thickness of the different legs of each component, some components will fall out if you do not screw it in VERY TIGHTLY (e.g. the resistor legs will fall out, as well as the leads for the battery packs. Otherwise it works just as advertised, and definitely bang for your buck in getting this whole kit at the price listed, instead of having to figure out how to piece together a laser trip alarm following a Youtube tutorial or something. Laser spy maze, here I come!
