Rating : - Philips Avent (SCD590) 2-parent monitor vs Grace Vibe
I also have the Graco Vibe, but I like this monitor best. It delivers as promised. I had a couple of concerns after reading other reviews (batteries and volume) I found that the battery life works as promised; I followed the manufacturers instructions for charging/discharging. The volume, with sensitivity and volume turned up,is adaquate for me (I want to hear everything), though not quite as loud as the Grace Vibe. The sensitivity is excellent; the volume is good if your surroundings are not too loud. THe range and lack of interference for this monitor however are much better than with the Graco vibe so it is worth the extra money. Also the Graco battery life is only 1-2 hour compared to 7-8hr with the Philips ("on"). I like the intercom feature for communicating between parents in a multi-level home. Also the lanyards (and belt clips) are a nice touch, and I like that the moniters charge in bases for easy drop off and pick up.
