"never having done anything like this before i found the installation of this vent really easy. the instructions are easily followed and simple to understand. remember to buy the adaptor as i thought it was included. i bought this to use with a bathroom extractor fan and found using this tile vent much easier for installation rather than drilling through a wall, the soffit on my house was too small to fit an extractor through it. i only had to remove 2 tile nibs which hold the tiles on the back of the batten. a good product which i can recommend for use on the right type of tiles."
