I was looking for a "minimally invasive" system for our downspout and be convinced by Speedy. Installation is very simple from Equip. The drilling tool is me indeed already broken when drilling into the downpipe (ie only the drill itself, not the hole cutter) was, but then simply replace it with their own drills. My water butt is not plastic but made of solid chestnut - there was the drill bit more difficult, but still works impeccably.
When the system is first installed, it collects water quickly and reliably. After two nights in light summer rain, the 150-liter barrel was full. I am completely satisfied and can the Speedy highly recommend.
