I've had the Avent Isis, Tommee Tippee and the Medela mini electric.
My favourite was the Avent Isis, so comfy and efficient.
The Medela was good for ease of use, although not as fast or efficient as the Isis for me.
Don't ever go near a Tommee Tippee, mine was flipping painful, like a torture device!
