RefLock?

Hello guys,
Right i know many of use have used/ will use lokring in there time, but i'm just wondering has anyone used this similiar technology called Reflock?

Same prinicipals with Lokring but instead of using copper pipe its aluminium which makes the cost of the installation a lot cheaper!
But then the fittings,inserts, glue & you have to use and special hydraulic crimper to press the fittings together

Has anyone used this method before?
Do you think old school way of joining ACR pipework is still the best?
I'm only asking these questions because the company i work for are now employing this method to two of our big VRV Installations.

Lets have a debate folks!:)


Thanks,
Luke
