Flomasta 25902SX Two Channel Programmer is rated 3.6 out of 5 by 16.
Rated 3 out of 5 by from Just works! Super easy to fit, dirt cheap.. Programmer is a little fiddly. The lid can push buttons when closing, but thats not really an issue as you only open it to program anyway. Works miles better than the broken one it replaced.

Rated 5 out of 5 by from Best product It's very easy to instal this programmer. Just unscrew my old (different type and model) and I can instal new one on the same rack. Menu very easy and clear. I'm very happy because I didn't expect that in this price I will get fantastic and easy to use programmer. What can I say? Screwfix all the time will surprise you :-)

Rated 1 out of 5 by from Flimsy Front cover very flimsy. Easy to accidentally push the buttons located underneath. Not suitable for older people. No screen back light.

Rated 1 out of 5 by from 2 Units, both developed faults Purchase to replace and old mechanical programmer. Unit has nice large LCD, although could do with a backlight depending on where you install it. Our first unit lasted 2 weeks, before half the display stopped working. No details were being displayed on screen anymore, the only remedy being to turn the unit off from the mains... Screwfix kindly replaced the unit for another, however that unit had a LCD that did not display anything unless you applied pressure to the screen itself. In the end screwfix refunded me for the product, and I have selected the Drayton LP522 instead. I will avoid the flowmasta in future and don't recommend it to others.

Rated 2 out of 5 by from fiddly programmer This is one to avoid.The one i got would not even mate to the backplate.The black buttons get triggered when you open and close the flap,absolute nightmare.

Rated 5 out of 5 by from Great timer Great little unit, took a while to work out the daily timing, but got there. Looks neat and tidy I've had 3 timers in 20 years this one I like the best, so far, time will tell. Great price great unit, hope it lasts.

Rated 3 out of 5 by from Loses settings on power fail If you plan to stick with a default programme (which includes, for example, 'on' at 6:30am) the this unit is a good price. If you set anything other than one of the default programs then settings will be lost on a mains outage. It could be I got a faulty one and the settings are lost by some malfunction, but I think not. No good for me, but worth a try and get a refund if no joy. The expensive 2-channel Honeywell seems to be unreliable too. If I weren't about to move house, I would fit a couple of electro-mechanical time switches instead.

Rated 5 out of 5 by from BRILLIANT For the price this is un-beatable. It took me less than five minutes to install it's presets worked straight away, I just had to adjust the time clock 1 hour. It went straight on to the existing fixing no wiring, no screwing or drilling, just clicks on.
