It is basically a china knock off of the CPR Bak Pak. It also comes with a no name china pump as well. The pump is made to look like a maxijet but it is not. Probably works fine but i would gather there really would be no custmer support.
Just looking at it, it looks exactly like a Bak Pak just like Captivereefs said. As long as it is built the same way on the inside as a Bak Pak is, it should work exactly the same.
I saw them at the HH backer pet show a few months back. THe build quality was Kind of rough if you ask me.I was not really impressed. There is only one way to find out though; buy one and let us know what you think!!
