Prompt and easy delivery from NiceBuys thank you. The downpipe diverter itself however is hard to install well due to its poor design. The overflow hole at the bottom that sits inside your normal downpipe below is very small. This has two effects: The diverter cannot be firmly fixed and easily wobbles and tilts which affects its function (which relies on the diverter being level). Secondly, during heavy rain the diverter gets easily overloaded with water and spills water over its edges. Defeating the purpose of having a downpipe.
So far it works as expected, but the fit on a rectangular downpipe is not optimal. The bottom is flat except for a small outlet tube, but there is nothing to keep the pipe aligned and can shift around. I used clear duct tape on the back.
The top doesn't fit very well either, with nothing to prevent in/out movement of the downspout in the diverter.
Black wasn't my preferred colour with all white downpipes.
Overall, it works, but I'll try to find a better fitting diverter if I need more.
