Slow shipping great tools.
Took awhile to get here but great tools from mastercool. I stripped the bubble (clamp) dies trying to do 3/8 stainless. It was .49 wall and way too thick. Should be able to handle .28 stainless. The does still work but leave marks on tubing now. Guess we’ll see how there warranty is.

Amazing Amazon!
The Mastercool kit is an addition to my existing Mastercool tools - brilliant tools to give a perfect finished result.The exceptional bit is that Amazon Prime facilitated getting this kit from Texas to Melbourne, Australia in four days and at a VERY good price!Amazon Prime has opened up a trustworthy international buying avenue for me I did not know existed.Well done.

Great tool
The actual tool was and worked as expected, it did a great job flaring hydraulic lines to connect to jic fittings. The only down side is that there is no case for all the pieces and there is no place to put them in the master set. So a case included would be a great asset
