I can not confirm the statements about leaks. The correct assembly is of course essential. When inserting the tube comes to 4 cm a resistance. Then the pipe sitting in front (!) Of the seal. This resistance must be overcome, and the tube may then be inserted further 2 cm. That's better, if one pushes back around the cut with secateurs possibly oval compressed tube. The best way to be before a mark of 6 cm from the interface. Then you know if it really "sitting".
I have the system now 3 years in operation with more than 20 different connectors and not a single leak. My pump brings the pipe system to more than 5 bar. If there something is leaking, you can see that immediately. And this review should be carried out expediently before bury ...
The system is certainly not cheap, but ingeniously simple and reliable.
