Very poor quality! I'm afraid that the waterproofing it offers is not of the IP44 class that it claims in the specifications. The rubber seals that are supposed to seal the entrances of the 2 cables are very thin, they bend and do not fit well together to "seal the hole". Overall, it doesn't seem to close the joints properly. It doesn't even have a base to support it, for example on a wall, nor anything through the holes (e.g. clips) to hold the cable in place and prevent it from moving and coming out. I'm afraid to use it outside in the rain. Fortunately, it was cheap and I didn't spend much money.
