The Allegro is great and an essential if you travel! It is portable, quiet, has a long battery life, you have the ability to buy extra shield kits and it is so easy to use!
We travel a lot and with having a breastfed baby, the idea of 6-8 hour car trips, stopping every few hours to feed made travel a lot less desirable. Now when we travel I can have pre-expressed milk bottled in the eski to give to her cold, OR, I can pump in the car and then give her the freshly expressed warm milk!
The pump sound is very subtle and doesn't interfere with the music being played in the small confines of the car and is also good for when at home expressing while watching TV.
The battery life of the pump has been great, I haven't needed to recharge it yet and I've used the pump over 15 times, still without any change in suction- I'm impressed.
Being able to double pump if required is a handy feature, but what I love even more about the extra shield kits is you can pump multiple times during a car trip (or at home during the day) by attaching the next shield kit - no more worrying about not being able to sterilise on the move!
I could go on and on about its comfort and effectiveness with expressing me, but I think you can already tell this is a great portable pump and I would recommend it to anyone without hesitation.
