I have a four-month old and use this monitor throughout the day as she naps (She is still sleeping in our room at night). We purchased this monitor at the recommendation of store clerks at our favorite baby superstore, and we could not be happier with it. We live in a condo community, so have the wireless signals from Wi-Fi and cordless phones from both our home and those of our neighbors. The digital signal is great, however, and we have never experienced any interference while using this monitor! The monitor has a sleek, simple design that looks good and it is very basic to use. I love that we don't have to surf channels to see which one would work best, as I have had to do with other baby monitors that I have used. The battery life is not great, but it is long enough to be convenient for me. It alerts you if the battery is getting low and gives you plenty of time to start charging it. The volume level of the monitor is pretty quiet, but it lights up to correspond with noise from your baby. The fact that this monitor lights up to correspond with volume as your baby cries is my favorite feature of this monitor. This is very helpful for times when there is a lot of noise and it could be difficult to hear the monitor -- like if we have friends over or if I am blow-drying my hair. A lot of my friends have had monitors that do not work well, either because of interference or battery life, but this has not been the case for us. We love this monitor and would highly recommend it to anyone! And, best of all, it is the same price as the monitors that I have heard don't work as well!
