IKegger for forced carbonation?

[SKBugs]

G'day all,
I was at my homebrew shop the other day inquiring about carbonating my small brew ciders and mead. In particular I was interested in carbonating 4-5 litres and thought that the IKegger might be the way to go. My guy reckoned that the IKegger and similar brands wouldn't carbonate so much as just force the contents into the glass.
Does this sound right? The smaller kegs with the CO2 capsules don't carbonate very well?

Of course it will carbonate. It's just a 50litre or 19 litre or any other size keg but in mini form.

It's how I started kegging.

But to be honest, I wouldn't go through ikegger, there are far cheaper options around and it's all the same essentially.
