Tommee Tippee Reassurance 6

Tommee Tippee Reassurance 6 - Very modern and sleek design to the parent & baby units. Simple to use, just plug and listen. Both units use 'AAA' batteries (as stated on the box) but not until you open the box and begin to read the manual does it tell you "not to use with rechargeable batteries!" That information could be more useful prior to purchase so that you don't go and spend £8 on a pack of 4 batteries for the darn thing! or you can decide before you buy whether or not you can afford to buy a monitor that you will need to purchase batteries for every week or so. I bought it hoping that rechargeables would be fine to use because we all know how expensive batteries are these days and how quickly we go through them. Like I said, the monitor is absolutely fine in every other way (especially the clarity) but the fact that they don't inform you on the outside of box not to use rechargeable batteries. I don't know how rechargeables would damage the units but they seem to think they will.
