I used mine a couple times and have had alot of trouble getting it to sync, range is less than 30 feet through my back door to the counter. depends on how you set it on the counter as to if it works. If you turn off the reciever you have tr re sync it with the transmiter through this overly diffucult door in the back that gives you the impression it seals up well. Then today I get a pop up thunderstorm and the screen now has water in it. It was working when I turned it off but who knows when I turn it back on. I swaped this in for a 13.00 taylor weekend warrior.... What a dispapointment. I am glad I bought a couple for backups on sale. cause this thing is not dependable. Anyway there are plenty of faults on my part, so maybee it is me but for this amount of money I expected much more. Just seems like if someone would take this basic desigh and make it to last they would sell much better..... Or at least I would be happier.
