This is honestly absolutely brilliant! the only downside is that it doesnt come with a manual but to be fair i copy and pasted it off of this website and saved it on my phone for future reference. they supplied a couple extra sensors and buzzers in case you break 1 or have a differwnt preference on which type of sensor youd like to use. all round great device.
