Pros: Simple replacement.
A replacement for one that lasted 15+ years. Hope this one lasts as long.

Honeywell ST699 Timer - Still top of the class!
Pros: ease of fitting - ease of use - fit and forget!
Cons: Sad that the back-up battery is seen as a non-replaceable item by Honeywell
This item was ordered to replace the original ST 699, which was suffering from a deceased back-up battery on the circuit board of the existing controller. Upon its arrival by first class post, it took me all of fifteen seconds to isolate, remove and replace the defective unit since it was fitted in the Honeywell surface mount connector backplate. It took longer to re-programme the timer than to actually remove and replace the unit! Excellent!

Honeywell ST699
Pros: See above
Cons: None
Easy Peasy - Changing the unit from an eleven year old similar unit with a failed battery pack took less than one minute, aside from re-setting the time clock!
