Honeywell ST699 Programmer is rated 4.0 out of 5 by 26.
Rated 3 out of 5 by from Exchange This was an exchange as the first one blew up after 15 minutes of use. Bought as a replacement on an existing Y plan set up. It is unusual for Honeywell products to be faulty but screwfix changed it without fuss.

Rated 4 out of 5 by from Simple fit Slots straight in as replacement part. Screwdriver only needed to release catches.

Rated 5 out of 5 by from A good proven controller If you want a reliable controller which is compact, easy to fit and simple to use for basic systems - This is (in my opinion) a durable product designed to last and do its job.

Rated 4 out of 5 by from Easy swap out but expensive Bought this as a direct replacement for a 15 yr old one. Easy to fit as it pops onto the old backplate. However, very limited functionality compared to other cheaper products. I wouldn't recommend it unless you want a straight, hassle free, replacement.

Rated 5 out of 5 by from Honeywell Programmer A simple to install programmer and noteably easy for housholders to use.

Rated 4 out of 5 by from Expensive but ok. This is an expensive timer compared to some. But it is ideal as a direct replacement. Easy to use and no issues with it.

Rated 4 out of 5 by from simple fix Easy to fit and wiring in a doddle. Clear operation features for every age bracket.

Rated 3 out of 5 by from Does the job Basic controller to replace a 4 year old failure which was to replace a 10 year old failure. Once you know where the release catches are it is simple to replace the front panel that has all of the functionality to save re-wiring a back plate (which is left in situ). Seems a bit pricey for what it is and like many items, the usable life before failure seems to get shorter than the last one purchased every time you buy one. Hoping this one lasts longer than the unit it replaces.
