I am a plumbing contractor and have been plumbing for thirty years so I have worked with a lot of different types of pipe. First when this stuff came out I was a little excited and thought it would really make gas pipe easy for install compared and after I did get to use it I was a bit different in opinion as when I install in new homes or open area where is not difficult to work in I was surprised to find I could install at the same speed or better using hard pipe, probably because I have done for so many years. It could be easier for someone with less experience to use it. So I will usually use the hard pipe over CSST and I'm referring to the type and not brand. I do use this type of pipe however to install in tight area's and something that I thing will make it faster for me. This brand as far as quality, I will say it is not the best one out there and because other brands do not have the washer inside for making the seal and several times I have had this tear inside causing a leak and where as the other brand makes a seal with out the need of any washer and just from the compression its self. but I still chose to use this brand most of the time because the price is almost half of the other one making it almost not a good option for anything. Now the last thing I want to point out is the certification they offer, this is most definitely something if you live in California you will want to get ahead of time as it is something that is required by the building department and you will have to give them a copy of yours for the final inspection, and if your not getting inspection first whether you are replacing or installing a new gas stub a permit you are supposed to have. If your not then at very least follow there instructions perfectly and should have no problems then but if you skip anything you could be placing your self at risk because remember you are dealing with gas and if you have ever seen the outcome of a natural gas leak then you know you most likely will say good by to your house as itr will take the whole thing up and make it disappear. make sure to do a pressure test and this means to place a gauge on the system and fill with (AIR !!!!) pressure and a inspection requires 15 psi for 10 min. and that means that if you see drop in pressure at all you should get a soap bottle and spray the out side of the fittings until you see bobbles and don't except any leak, 15 psi for 10 min. that doesn't mean if it only drops 1 psi in that time its good, its not that hard to fix a gas leak if you have gotten this far

Rated 4.0 out of 5.0 by OregonContractor Great alternative to rigid piping
I put this in my crawlspace to replace old rigid piping. This made the job go much quicker in the confined space with many wires, ducts, and plumbing already in place. You need to buy their cutter so as someone who will not do this as a trade that was a expensive add-on but still cheaper than measuring and having multiple black pipe pieces threaded. I would like to have seen better instructions about code issues regarding how often it has to be strapped to framing.
All in all this is a great product. I need to upgradeto 1" pipe from 50 year old 3/4" black pipe because I needed to increase volume of gas flow for a new tankless water heater. The fact that the wall is so thin helps with that increased volume.
To install you use the cutter to cut the pipe. Then use a knife to

Rated 1.0 out of 5.0 by Tom Bad Design
Let me say first that I owned a marine repair company and worked as a pipefitter so I know how to install fittings.
First problem - The problem with these is that when you cut the plastic back (2 valleys) you have to slide the connector over the plastic in order to clamp the retainer ring. This tears up the O-ring inside and causes leaks. Bad, bad design.
Second problem is that after I installed the line and started to check for leaks I heard a hissing sound and gas was pouring in my house! There was a pinhole in the CSST about a foot away from the connector end. All I did was slide the CSST through a hole in the wall. Either it came to me defective or this stuff is so fragile that brushing the outer jacket up against the wall while putting it through the hole caused the damage. Either way this stuff is WAY to fragile for me to trust my life, and the life of my family. I returned and am going back to pipe....

Rated 4.0 out of 5.0 by Scoop Easy to run, be careful with connections
Much much much easier to run than black iron pipe. Just make sure when you cut the pipe it is a perfect cut - clean and not crimped. I had a big leak at first, recut the line and it went away. Also be sure to watch the video - there's a specific way to tighten the fittings so that you don't damage the compression surface and cause a leak.
