Query: Doberman should be ashamed!

I didn't buy this from Amazon, but feel that anyone looking here to purchase one should be warned. This is at best is a toy and should be avoided at all costs. The range of the sensor says up to 15 feet, but It takes being anywhere from 3-8' to trigger, and this distance does fluctuate and as stated the best I can get is 8 foot. The most disapointing thing is the little speaker for the siren/chime. My kids leapfrog radio has a louder speaker than this. The chime is poor at best and the siren is laughable. The manual states 100db of output, and I work in the audio industry and know that this could never be this loud even if lightning struck it. Honestly my speakerphone on my cellphone is about as loud.Doberman wasted their time and my money. False advertising possibly.
