I've used this hose for a year, that is, both winter and summer.
It's very flexible and light weighted that I don't feel anything behind nail gun.

Have noticed one problem in summer. The surface of hose is a little stikcy, so it tangles each other easily. Once they get stuck together, I have to spend quite some time to untangle it. If you maintain the hose straight, it'd be ok. But when I move the hose here and there, it tangles more than rubber line in summer.
In winter, it's stiffer but still more flexible than average rubber hose.
One time, I dropped 2x4, and the hose cracked easily. Since then, I have to pay extra attention to protect the line than other hoses.

I've used many hoses, including all kinds of rubber hoses.
Overall it's a good hose. But it tangles easily and suface is not so strong, I don't use it extensively, only use it in short distance and/or simple jobs. Don't recommend this hose for any tough jobs at all.

Threaded fitting snapped with very little pressure when I started to thread on the quick disconnect. Obviously defective. We needed the hose that day for a job we were on so we cut it and put in a hose barb with replacement threaded fitting. Unfortunately the strain relief was attached to the dfective factory installed fitting so now the hose probably won't last very long.

I've been using this for a few months and the lighter weight and more flexable hose compared to conventional shop air hoses has been very nice in my home shop.

True this hose is remarkably lighter and more flexible than you'd expect, but these are overall improvements to rubber. They just take a little getting used to.

I almost had to give up using air tools as my elbows would ache badly after a day in the shop. I tried this hose hoping that the light weight would reduce the drag, and it worked like a charm! I also put swivel fittings on all my air tools, and the combination of the two products has reduced to zero the excess strain.

The hose is extremely durable, and has handled constant pressures up to 120PSI without flinching. I have never had a problem coiling or uncoiling it in any temperature, and I can store 2 hoses in the space of my previous one.

All in all, I'm glad I switched, and highly recommend this hose.
