Honestly I held out for time buying tool like this, and once I picked it up and used it couple times, it became necessity on every install.
The only issue with it's it does not work on 3 8 copper because the copper does crack every time..
No problem though because I just keep one of those 3 8 impact bits that swadges the 3 8 in about 15 seconds..
No long term trial yet and this unit seems to be doing just fine for now and of course the lower price than brand name ones makes it better..
So after 9 months with the swaging kit I bumped from star to star because it has worked very well and the hydraulic pump aspect is still working very well..
I also purchased bender kit and between the two it's rare that I need copper fitting - maybe 90 deg elbow once year or so..
This is not brand name product, except it seems to be doing just and one..
One thing to note is having to swage pipes coming out of wall or ceiling the brazed part of the pipe is always facing you so that visual check of your brazing is piece of cake..
