I got a similar kit from my LHBS that did not include the compression fittings, just worm gear clamps to tighten the hose like you describe.
It was a miserable failure. Leaked like crazy. I went out and bought the fittings and it's all better. Well, almost---one downside to the compression fittings is that they have a much smaller inside diameter than the tube/hose they attach to. If I turn the water up too high, I get a bit of leaking on the hose nipple side. But I've had zero leaking on the compression side.
The kit worked well for me. One thing I would recommend is obtaining a proper tube bender for the small-radius bends. Wrapping it by hand around a form to make most of the turns is fine, but one can very easily crush the tubing or, worse, hyperextend one's thumb trying to make the small-radius bends at the ends. And trust me, the trip to urgent care is far more expensive than a tube bender.
