Good alternative to armoured cable
Used this when replacing a pond pump which has the cable running underground. I have used armoured cable before but this means having a join, underground, close to the pond. Getting a waterproof join underground is not impossible, but it is difficult. In this case, I removed the plug and threaded the cable though. It will not pass through long lengths so I used 3m lengths sequentially and butted the joins up. Then I buried it. It is working fine so far. I suspect it is weaker than armoured cable so know where your cable is buried and take care when digging in that area (turn off and unplug to be sure).

Good conduit
Arrived on time. Correct length and diameter. Robust, yet flexible. Perfect for protecting an electrical cable from mechanical damage and/or weathering. There wasn't a draw wire, but I knew that when I placed my order. Though a draw wire would have been handy, it really wasn't difficult to thread the cable through. Happy with my purchase.

One needs a draw wire to enable long cables to be pulled through.
It did the job for which it was intended. It protected an outside underground electric cable from rain water and easily making contact with adults or children who did not know it was there.

Conduit appears to be smooth inside to allow cable to be pushed through 20m length
This review is for the 1STec 20m 20mm External 14mm Internal Underground Cable Conduit Ducting. I found the ducting to be tough and durable and fit for purpose to be used externally. I fixed part to a wall using 20mm P clips purchased elsewhere and the rest was buried underground with part run along fence on the ground. I needed it for runningh ethernet cable for electric gates intercom - importantly it is possible to push the cable through the conduit by hand but you have to have the conduit pulled very straight with one person pushing the cable from end. It helps if its held on a downward angle as well and the cable slides through with a bit of shaking every now and then as the conduit appears to be smooth enough on the inside.
