Viva Adjustable Dual-Flush Syphon is rated 4.0 out of 5 by 7.
Rated 1 out of 5 by from Not compact Item described as compact but doesn't fit a tapering cistern. Collected, compared with standard siphon, same base size, handed back over the counter.

Rated 4 out of 5 by from Value for money Bought this based on the excellent reviews and it does exactly what it is designed to do. The adjustable height feature is great as my toilet cistern is an unusual none branded design/shape ....this one works fine so I'm very happy. Make sure you consider replacing the inlet valve assembly and close couple seal if you are replacing the syphon unit a load of hassle later on. Great product at a great price.

Rated 5 out of 5 by from Flushing good Great value for money. Duel flush makes saving water easy, apart fromn the fact you need to hold the handle to save water, would have been better if it was fush and relese for short flush. Will take some getting used to and training the kids. Only down side was getting all the water out first. Then just 30 minetes to fit. Last one had lasted 30 years. Lets hope this does too.
