Connecting outdoor security light
I bought this to connect my new LED outdoor security light to a main supply easy to connect and waterproof I used cable clips to anchor to the wall I’m giving 5 stars on how easy to set up.

Compact design
Purchased to connect a new security light to existing wiring. Didn't want a full size connection box, and this does the job well. Would suggest that you feed in the wires at either end but don't tighten the sealing ends until you have wired everything up as not huge amounts of room to move cables around etc. It's been in use for over a months and all seems OK, no ingress of water and light connected is still working well.

Updated. Seems to be a good quality product. IP66 rated so should over good water protection
I've used this to join a few electrical wires for an outdoor light. First impression is its a bit plasticky but things do seem to fit well and my wires are held securely. Reviews seems good and it does have an IP66 rating i.e rated as dust tight and protected against heavy seas or powerful jets of water. Time will tell how weatherproof this is and will be addressed in a a long term update. Update: 2 months. All working well. I did put some silicone around the the entry points and closures for added waterproofness. Update: it's been raining in Glasgow continuously for coming up to 4 weeks! Windy as well on occasion. No problems with this little box so far.

Waterproof and solid.
Great. I replaced the included block connecter with Wago in line connectors as I like to use cable ferrules which are too large for the block. Seems very waterproof and mounts solidly.

Did the job
I had to change my outdoor security light and the new LED one had a sealed flying lead so this was required to connect up to the existing mains cable. Easy to use and so far seems waterproof although I may add some extra waterproof tape around the cable glands as prolonged outside weather exposure might cause them to become brittle in time. It has a gasket between the lid and box and also clicks shut so it should be fairly waterproof. It is a good quality and a value for money product.

Fiddly to install but does the job
Got one of these to power / switch garden lighting and be smart controlled by Alexa etc. They're IP rated so are meant to be weather proof however the rubber olives in them didn't quite cater for the thick rubberised outdoor cabling we had. Additionally when connecting them up internally there's very little room to work with so you need patience and to be careful with the individual cable lengths of the live and neutral etc so it all fits in ok, in both the feed and outlet sides. Pairing with the WiFi was the worst part. Getting it into pairing mode is a pain as you have to mess around with turning the power off and on to do it. Given the feed for that is switched inside the house that involved lots of running to and fro before the little blue light indicated it was in pairing mode and I could use the app to get it onto the WiFi and registered. Otherwise it works great and having Alexa / smart controlled garden lighting is quite neat.

Works good. I have it mounted to a pond light that is hidden away. I would t submerge this, but will do the job to keep water out from rain.
