Opella Dual-Flush Siphon 220mm is rated 4.5 out of 5 by 362.
Rated 1 out of 5 by from Broke on installing Fit is ok, but the spigot at the bottom will not stand much tightening and broke on installation. I ended up cannibalising the unit for the return spring and rebuilding the old one which seemed to be made of much stronger material.

Rated 5 out of 5 by from Top Quality low cost Siphon These Opella siphons are a very good product that are very commonly used on older type toilets with flush handles. Note that they are 220mm high, which will often do cisterns that require internal overflow ability, using the siphon. My long experience of these siphons is they are one of the best and very reliable. At the price, they are a bargain and I intend to buy more for spares. The only better siphon is the 2 part types that can be repaired without removing cistern (on close coupled toilets), but they are more expensive, although still something to consider.
