I bought these on the strength of T Griffin's review & I thank him for it. The Brennenstuhl sockets are very well made, with a nice transmitter. They are also quite compact, compared with my previous remote-controlled sockets. The transmission range is also good: I can operate the sockets from anywhere in my house. A nice touch is the red indicator that lets you know that the socket has turned on. Some other brands don't have this feature, which is a pity as it's quite useful.
Setting up the sockets is fairly easy, but some people may not agree with this. To set them up, you have to arrange a row of dip-switches on the remote, then remove the covers on each socket & set them up individually. As I am used to setting up electronics, it was easy for me, but I envisage that inexperienced people could struggle for a while. You also need some small Jeweller's screwdrivers (or similar) to facilitate set-up.
It would help if Brannenstuhl supplied the sockets with the most popular setting already programmed in, then they would work sraight from the box. Another point that Brannenstuhl should look at is the 13 Amp socket. With a name like Brannenstuhl, you may guess that these sockets originate outside Britain. When you plug in an appliance, this becomes more obvious, as you really have to apply pressure to get the plug home. This seems to be a slight design flaw, as the UK earth pin is supposed to open the Line & Neutral shutters for smooth access, & this doesn't fully happen with the Brannenstuhl sockets. It isn't a major snag. but, if you purchase these sockets, you should be aware of it.
In summary, these are the best remote sockets I have used to date, & I have reviewed three types for Amazon. Just bear in mind the (very minor) problems. If Brannenstuhl sort these out, they are easily worth 5 stars
