Which do you think? I had a cheap one lasted literally 2 froths, waste of money, mind you it was only £3 but it did the job even if it was only twice. Looking for a better one and I found this Andrew James hand held that looked the part but DH thinks the electric one would be better. Only going to use it for the odd latte so I think the electric one is too extravagant unless you MNers say my life won't be complete without one!
I have a aeroccino for my nespresso machine and I love it. Used it for all sorts, making formula (probably not recommended, though it does heat to 70 degrees), milk for orphan lambs, milkshakes for the kids, babycinos - everything! On that basis I'd recommend the proper electric one - we had a hand held one before and it's nowhere near as useful
