Pros and cons

Pros

Combines a timer and fused spur in one fitting intended to replace a standard fused spur.
Boost and Advance/Override offer temporary control without changing the recurring schedule.
Customer feedback reports ease of programming, readability and fit in an original back box.

Cons

What to know before buying

Listing details to confirm

The specifications are inconsistent: the details list dimensions of 120D x 40W x 40H millimetres, while the description gives external dimensions of 38mm depth and 85mm length/height and 85mm width. Check the required fitting dimensions before purchase. The listing states a 25mm minimum back-box depth, recommends a qualified electrician, limits the load to 13A (3kW resistive), and says the timer is not suitable for discharge lighting. Battery retention of up to 4 weeks is a stated claim during power cuts.

Customer feedback highlights perceived ease of use and programming, readable display, straightforward installation and fit, including use with immersion heaters. These impressions align with the listed daily schedules and illuminated display, but do not establish fit or installation suitability for every wiring arrangement. Aggregate ratings are mostly five-star, though lower ratings are also present, and the scores alone do not explain individual experiences.
