I've got both a Ridgid and Nibco unit like that, never knew Ryobi made one until now. Smaller pipe I think a manual crimper is faster, and I do have the little pillow block contraption for close quarters too which works awesome but takes quite awhile so if you have quite a few crimps to make takes forever. With that said, the cordless ones don't fit everywhere either and they can be a painus in the anus to drag around as they're heavy and the jaws are very heavy and bulky. My Ridgid one is lighter and faster but will squash the crap out of a copper ring as it's designed for the Viega SS collars which are smaller, so I've all but stopped with the copper rings. The Nibco does a great job with them though as long as you take the time to keep them square. Different animal trying to keep the ring in place while holding a 7lb tool versus a 1lb manual tool so they do tend to get cockeyed sometimes. If I were doing it again, I'd probably aim for the Milwaukee tool. $300 more than the Ryobi but the Milwaukee is tried and true AND can use copper press jaws as well
