Aquarium syphon

[neilmcca]

I'm gonna get cracking on my wine kits shortly and was wondering if this is suitable for my needs,

i will be using it to transfer the wine from demijohns to bottles.
the demijohns i have are approx 4-5 litre capacity and the necks are 30mm wide.
if someone has any suggestions for a better alternative, i would be grateful.

Neil.
