3/8" - 3/4" PEX Crimp All Tool Kit

I used it with 3/4" & 1/2" PEX. Crimps perfectly consistently every time, once calibrated for the size, you're working with! Highest quality tool should last many years! When beginning with a new size, adjust for a very loose crimp and tighten adjustment 1/8th turn, per crimp until crimp gage says 'GO'. FOLLOW adjustment and size change INSTRUCTIONS CAREFULLY! Insure crimp rings are completely inside jaws & that ring, pipe and fitting are properly in position, immediately before crimping. Must recalibrate tighten adjustment when changing sizes. Tool is 15" long & handles open to 22", plan your job accordingly. I believe this tool should be no more difficult to use than a similar tool by any manufacturer.

works ok. definitely not as nice as the viega (understand of course its less than half the price - you definitely get what you pay for with this tool). its cumbersome to use and not as handy as one would think (its actually easier to use two separate tools of two separate sizes, i.e. this is definitely not a time saver. setting the crimping compression is not intuitive, there are too many different elements to adjust and in my opinion the viega gives a much more secure compression. i also feel like one is bound to lose pieces and or they'll wear out over time (too quickly). one is definitely better off going with the pricier viega crimper, the difference is night and day in this reviewers opinion.
