Review title: Not even working at 30 feet
Product review: In the product features, it says: "Sensor can be stationed up to 100 feet away...". Well this hasn't been the case for mine at all. I couldn't make it work properly at 30 feet (it wasn't stable, losing signal every now and then for no apparent reason) and I followed all the instructions and had brand new batteries. Either my unit was defective or the signal strength needs to be adjusted for all units when built. I returned it.
