Query: not so warm review

AVENT has great products however this one is not one of them. Here are a few reasons I feel this way: This warmer lacks an "on/off" switch and must be unplugged with each use (which with early a.m. feedings is not always easy to remember). The absence of this feature also requires unit to be placed near an easy to reach outlet at all times. Due to the absence of any premeasured units for filling water into chamber, overfilling causes bottle floating and messy clean-ups. Lastly the specified times for proper warming in manual is not always correct , thus overheating is usually the result if you walk away.This product does have a few good points: It fit almost all bottle types (both reqular, disposable and wide mouth). It's easy to clean. It allow fast warming of breastmilk (frozen),formula and baby food(that has been refrigerator). and finally IT'S BETTER THAN WARMING UNDER TAP WATER!!!
