Honestly, I expected to get what I paid for and once it arrived I consider it a good dealThe few optical sensors types I needed were included, they work, so again, good dealThe rest I'll test one day, if they ALL work even better.What you need to know:-> cons - they arrive in a bag, entangled, some pins bent. If you want guarantees, a similar set I bought before for 3x the price, had each sensor wrapped in a separate antistatic bag.-> pros - if you just need some prototyping and replenish your sensor inventory - great bargainRecommendation to the manufacturer :- it would be really nice to try to isolate the pins somehow - I use foam sticks, or alternatively , just use tape

Not only were they packaged horribly, causing damage to multiple items, but the ones intact are full of corrosion and 3 failed testing before I threw the whole lot in the trash. Never again.

Product arrived as a random jumble of parts in a plastic baggie (see photo). I count 37 in total but I don't know if they are as advertised until I google every part number. I suppose documentation will also have to be googled. None appear obviously broken, but many have bent LEDs or other components, not sure yet if they work.

1- All sensors came jumbled up in a wad wrapped around with bubble wrap. This meant all the pins were bent, some sensors were damaged.2- I am missing the relay mod3- Comes with a laser emitter but from what I gather no laser reciever mod4- Poor quality

You need to put into use and not touch again. Very easy to damage. No documentation. Some did not work as expected, but may be my fault. Not sure who is the right target audience for this.
