Flex-Drain 51710 Flexible/Expandable Landscaping Drain Pipe, Solid, Feet, 4-Inch by 12-Foot

Was not delivered on the time quoted. Still not used it.

My ferrets love this!

Good value

This was quite pricey and took quite a long time to get here. Moreover if I was using this as some kind of liquid drainage, it arrived with two small holes in it even thought the packaging was unbroken, and I would have been even less impressed! As it is I'm only using it for the heater matrix cold-air inlet ducting on a classic sports car. The holes look like they have been chaffed through while in storage or transit before it was event sent to me; Amazon's packaging was fine. It's also worth noting that the 4" internal diameter DOES NOT refer to the whole pipe - but instead only to the moulding ...at one end! Luckily I've still been able to use it, but nevertheless Caveat Emptor!

these are too big for the standard UK black guttering, they are sized for the brown guttering which is bigger so a wasted purchase on my part, also has a hole in it on arrival
