Our Favourite Product Review:
…I recently purchased an exterior SD5 large wall mounted letter box sku.DAWAL508COP/ Colour Copper. Today, I am writing to say how pleased I am with my purchase, it is all I wanted it to be with regard to being the correct size for the larger letters I receive such as magazines which enter the top flap easily and the box is completely water proof, very important especially in a year like we are having. We have large wooden gates on our property and we fitted our box onto one gate,the process being simple to carry out and one thing which impressed me was the fact that the screws were magnetised and really made the job simple with no fiddling about looking for dropped screws. So, to sum up, the box is very well made, easy to fix, looks good, the price was right and my postman likes it too. Oh, and talking of postmen, the delivery was very fast as well… Mr Laurie
