Query: This is the Greatest Product ever!!!!

This product is exactly what all the reviews say!!! It really does work !!! Finally a product that does work. We just pluged it in and that was it!!! One of the reviews said it took a long time to set up, thats not true!!! They might have turned the sensitivity dial by mistake. Just leave it at the factory setting and you wont have a problem. The only problem we and many other uses have (and its really not a problem) when you take the baby out of the crib or bassinett you have to remember to shut it off or it will sense no movement in the crib and sound the alarm. To us, it shows that this thing is really working!!!! YOU MUST BUY THIS!!! TRUST US, YOU WONT BE SORRY!!!!
