You did the right thing for several reasons.
1) You bought something from them. They are probably going to go back to work tomorrow and try selling stuff again, which means they aren't standing at Centrelink with their hand out.
2) You're trying out a lift kit that may or may not be any good. It's always good to do a little trail-blazing, I've done plenty in my time, now I can sit back and watch you do some. Even if the thing is junk, you can say you tried it and you can hold your head up high.
3) The kit might be bloody good!
I have no idea if Snake or Calmini or anyone else actually manufacture their own stuff, so many are into branding these days - Nissan bullbars are made by ARB in Australia, Nissan towbars are made by Hayman Reese ... so who really knows. If they are making a good product and you're happy with it, that's bloody brilliant and not much else really matters at the end of the day.
