Rated 5 out of 5 by from Quality item Honeywell have been in the electronics industry for many years and they know how to make quality products that are extremely reliable. This programmer replaced the same model that has been in constant use for over twenty years. It is easy to install,program and use. A little bit more expensive than other programmers but well worth it if it meets your requirements.

Rated 5 out of 5 by from ST699 review A good reliable product from Honeywell. A simple twin time controller for Heating & H/W. Simple to install and to setup. This controller been about for many years, had to change one last week, which was fitted 16+ years ago. Clicked out old and Clicked in new, backplate was identical, no changes to wiring required. Can not fault product for simplicity and reliability. A little more expensive compared to competition, but a few extra £'s for like for like and simple install, worth the extra + no retraining or revisit to customer.

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.
