Query: Mine is in the trash - don't put your money there as well!

After about 6 months of erratic operation [even on the AC power supply], and burning up alkaline batteries quickly, it was finally placed to rest in the appropriate trash receptacle. Save your money, hang a tennis ball on a string and align it with the place you wish to park your car. You will regret buying this thing - believe me now - or believe me later - your choice.
