Worked beyond the 20" listed range when we tested.
Ours worked to about 30", but with less tolerance for misalignment at that distance.

Cat water fountin
My cat can now jump up to the bathroom sink, blocking the ir beam to trigger her own water fountain. She also likes BBQ and wild fish. Not spoiled at all.

Used for Samsung icemaker repair
I used the emiting component to repair a Samsung Frenchdoor refrigerator's icemaker. Samsung does not sell this part separately so hey want tou to buy the whole auger. A little bit of research pointed me to this product and the fixing cost was 1/10th of the whole auger element. It's been 2 months since I repaired it and it's still running fine!

overpriced but good.
I could have got this cheaper on an electronics site but had quicker and free shipping on prime.
