This monitor has been nothing but trouble since we bought it. It switches off frequently for no apparent reason, then switches itself back on again. The recharge dock does not work and the batteries will not last more than a day or so. The volume is also an issue, you have to hold the unit to your ear to hear anything.
There are many features on the unit such as talk back (a nice feature), Lullabies (ok, but there are only a few very short sung ones), nature sounds (terrible noise!)and tempertaure (handy but not sure it is accurate)
I think this monitor is a waste of money and if there comes a time to buy another one we will choose something more simple and trustworthy!
