## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good value
  

*by M***S on Reviewed in the United Kingdom on 21 April 2022*

Bought as a replacement for my old ST699 (see photo). Not a straight swap, mainly because the physical size of the unit and mountings are different - especially as mine was located between two other switch boxes. The actual wiring was easy and there are plenty of instructions on the Internet showing the two wiring diagrams. The delivery was very quick which was much appreciated as we had no hot water and heating due to failure of the old unity. Excellent service and a good price from this seller.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Genuine Honeywell replacement
  

*by E***S on Reviewed in the United Kingdom on 27 October 2023*

Easy to fit, just separate the carrier from the unit and then hook it onto your existing carrier already under your old unit.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    The LCD viewing angle is not adjustable, and wrong if above eye level
  

*by D***T on Reviewed in the United Kingdom on 14 December 2021*

This product was a replacement for an (old) Drayton Tempus 7 timer. Fitting was easy. Setting up was easy. It works well.  (It was NOT made in China !) It also looks good.The LCD display was not easy to see or read with the unit mounted above eye level. It was too bright with poor contrast. I stood on a stool to see it.
