I wish I could write a glowing review for this product, but unfortunately I cannot. We've had this lock for about one year. Our phones are Android based so we still have to relay on our fobs to open the lock The battery n the fob lasts only maybe 10 days to two weeks and needs to be replaced. Needless to say, we haven't been using the keyless entry, as the fobs are usually not working. I've spent $$$ on batteries that don't last. Still waiting for the Android App, which doesn't really seem to be coming. So far, my husband and I feel this product was a waste of money.
