Works perfectly and the price is right
I am quite satisfied with this unit. It is small, compact and appears quite well made. it comes with it's own batteries as well. I have not had much time to try it out yet, i believe it will perform nicely as i have given it a trial run. it performs well even through walls. will have much use for such a convent device. and a very good price.
It arrived when they said it would - does exactly what I want it to do, all at a great price.
It didn't really meet up to the distance that they advertise. But overall it's a good product and well worth the price. The only improvement I would like to see is the red LED being much brighter on the receiver when it triggers.
