Bests & Worsts Reviews from Amazon

I thought by this costing so much more than other cheaper options meant it would be a great product, but look over the reviews and you'll find it has the same problems as the cheap stuff. I have a 30 foot driveway and even on the lowest sensitivity level of 13 ft, it went off every time a car drove down the road. I tried adjusting it a bit and then it detected nothing. Also when it was detecting everything, if I walked slowly up the driveway, it wouldn't go off half the time. So no matter how much I played with it, it either didn't detect some things, or went off way too much. And the stupid chimes... You tested this for 2 years and still thought this was a good idea? The chimes are awful! Who wants to hear OVER 2 MINUTES of Jingle Bells every time a dog walks in front of this thing?!? There should be more short notifications, not full songs. Finally, their "AWESOME SUPPORT" isn't that awesome. I tried calling at different times, when they first opened and during the day and could never get anyone on the phone - it just goes to voicemail. Thankfully it didn't take me long to figure out this wasn't what it was hyped up to be, so I'm returning now.
