Came with parts that didn't fit together. Contacted mastercool, they told me to contact Amazon. Amazon was kind enough to give me the option of returning or a partial refund. Mastercool not only shouted sitting that didn't work, but didn't stand behind their product.

As expected. Look hight quality. Some scratches on all brass parts but nothing that can compromise the integrity of the tool. Im planning on tested this comming weekend and will let you know if there is any problem. Kit arrives complete... So... So far so good.
