Hi UF
Nope never used an electric one, truth is I don't really like using my electric deep fat fryer, much prefer the stove top.
I think the advantage of say the Russell Hobbs Aluminium 4ltr is its a really good all round cooking pot, the pressure part is just the added bonus.
I have loads of pots and pans, but I usually make a grab for this one.
I cook all my Handi Curries (on the bone) in it and its spot on.
cheers Chewy
