Drayton LP522 (Mk4) Programmer is rated 4.3 out of 5 by 41.
Rated 3 out of 5 by from Another Failed Unit The product has good features and is very easy to use however this is the third unit I have replaced - mine and several friends ones. Living on a new estate we see these programmers lasting about three years - good for the trade but not for the users. Refitting is a very simple job, just two screws to be loosened and takes under five minutes. Were the original ones a bad batch? We will see after a few more years.

Rated 4 out of 5 by from Rebranded Drayton Controller Main annoyance I found is undoing/ securing 2 small captive screws at base to secure programmer to backplate. Why of why don't manufacturers make more accessible? I appreciate they can't go on top because of the electrical terminals, but surely having one on each side could be an option. The Grasslin it replaced, had one large affixing screw at base, which was just about doable. The 2 small screws on the Lifestyle product are much smaller & hard to see on my kitchen surface, especially as they're partly recessed when screwed in fully.

Rated 5 out of 5 by from Great Programmer Good value 2 channel programmer. Having tried many, I have found this to be the most reliable and its features most easily understood.

Rated 5 out of 5 by from Excellent easy to install! I bought this programmer to replace an older Siemens programmer, the terminals were easy to connect wires to, it was very simple to programme the on and off times for the customer and was simple to show them how it works Definitely recommend

Rated 5 out of 5 by from Highly recommend I bought an LP522 earlier verson 10 years ago and it has worked reliably ever since, but like all things finally needed replacing this week. Next day delivery, fitted in 5 minutes to the existing back plate and 5 minutes to change the standard programming. Pretty good and I see the mk4 now has a boost and holiday setting. Pretty good yeah!

Rated 5 out of 5 by from Straight swap. I had to replace my old Sunvic controller quickly. This pushed straight into the same backplate and was working within 2 minutes. It has 3 On/Off times, a backlight and even a holiday mode. Absolutely brilliant for the price!

Rated 5 out of 5 by from Good Product Great Product easy to fit at a good price. Marked down on reliability as 1st unit didn't work out the box and i had to go back to store to change it.
