Literally received in the mail today. Was excited to try it out. Grabbed my Milwaukee drill, opened up the crimp kit box, laid down the instructions, grabbed a 3/4" crimp and went straight to work. It was the very first "attempt" and it took less than 10 seconds. I think I'm sold. While I cannot attest to the longevity of the products I can say that in the right hands this crimping tool can be a huge time saver and has been well worth the wait. I look forward to buying and running them. It is also a flare tool. I am in the HVAC trade. This crimping product will definitely find a place in my tool bag!
