Push button flush on toilet cistern?

Are push button flushes on toilet cisterns generally any good, or is it best to stick to the standard handle?
B&Q (at www.diy.co.uk) have one but I'm wondering if there would be any issues fitting it to a relatively new cistern.
Ta, Phil

If you mean the flap valve type.....
First, you will need to remove the cistern to exchange the syphon for the new flush.
Not particularly difficult; but I _needed_ to do something to trigger the change.
It seems to flush better. But I'm a bit worried about the system - in the commissioning, ths flap valve stuck open once or twice. It was easlily adjusted, but as I'm on a meter I sometimes wake in a cold sweat thinking about it!
If you want to change, think about the inlet side as well - I use a fluidmaster (I theenk... it's been some time) and like it, but there are apparently better ones, with a bit of luck about which out you will soon find; (we're a bit pedantic about our granma these days)

Hmm. Interesting. My experience with the US version of these has been that the life span of a properly sealing flap valve is relatively short. 1-2 years. FWIW.

Thanks,, that's cheered me up no end, I don't know when I'll get anothyer night's sleep.
I also forgot to mention the possibility that the boss on the button surround may be incompatible with Brit size cisterns; mine was, but I bodged it e=reassonably easily

Managed to arse up cutting the threaded stick off after not reading the instructions properly, ended up araditing three bits back on, been using it for a few months now without any problems at all.

I got a call from a family friend the other day saying the toilet was leaking. I poped round there and found the cistern mech wasn't screwed down tight into the ceramic cistern. I turned the water off, flushed the cistern, bailed out what was left and removed the plastic cistern mech?
The reasons it was leaking (apart from not being tightned down fully) were:
The hole in the ceramic cistern was quite a bit bigger than the plastic thread (probably 3mm all round), alowing the fitting to move off centre.
The rubber washer was quite narrow (not 'thin').
The flange over the washer had a 'flat' in the moulding leaving about 1/8" of flange at that point?
The local plumbers merchants took the old cistern out the back and tried to find one with a wider flange / washer but said they couldn't find one. I asked if thy had a Dual Flush one, he did and it had a much wider flange and washer! (Doh!).
I took it back, fitted the washer and bound the fitting with slit down PVA tape to make it fit (and stay) in the middle of the hole in the bottom of the cistern and tightened the backnut etc. Filled tested, no leaks ;-)
The Dual flush cistern I fitted in our place 15 years ago works:
Full flush: Push and hold Half flush: Push and release.
This new one works the other way round.
Points.
Why do all these (mainly plumbing) items seem so poorly engineered these days?
Is there a 'rule' these days re the working of Dual flush units (half / full, hold or not?).
All the best ..

Oh, and the handle was seized in the plastic bush .. now it's working nicely .. ;-)
