Leaked after 2nd Use
Size: 50-Foot, Style: Expandable Fabric
It leaks. I read many reviews and finally decided on this Camco EvoFlex water hose to use with our new travel trailer. I loved that it was flat, light, and flexible. On our 2nd campng trip it started leaking. The water was seeping through the hose near the connection to the faucet. (it was not dripping from the faucet connection) There must be small holes in the hose. We did not notice it at first because it was so slow, but after a few hours we checked on our hook ups and we noticed water puddling and dripping down the hose. Luckly we had a back up that was not this brand that we switched to. We tried it again the next day hoping we had just set it up wrong, but it continued to leak water through the hose. I was disappoinnted because this hose was what I was initially looking for.

Awesome Hose for the Price and the Perfect length
Style: -20-Degree, Size: 12 Feet
We loved this product and was so great over the winter. It is so think and does not freeze over the winter. Temp was 0 and below and it had no issues. The length is perfect for a camper hookup and you are not always tripping or having a bunch of hoses laying around. It was so easy to use and install. The hose is stiff so it does not kink but is easy to move around. It is very thick so it has held up well.

good hose
Style: -20-Degree, Size: 25-Foot
I installed it about 2 weeks ago, after reading negative reviews, I was prepared for the worse. I did as instructed, kept the thermostat sensor next to the water source and plugged both ends, however the middle of the body of the house was lightly still coiled. When I tried, the water was leaking from under the insulation, where connected to the water source, just as I saw it in the negative reviews. Then I remembered, the instruction clearly say, the house must be uncoiled, so I disconnected, and stretched it out completely in a straight line taking out any kinks, then I took the ends and plugged them in the outlet and inlet. Tested it again and NO LEAK, it works perfectly. That night, it was 25F degrees, the hose was warm to the touch and no leak (the pressure in my sink faucet doubled, I suppose my old hose was not as efficient as new one, etc...). So, it works. I must say, that the instructions, indicate that the heating element turns on below 50F degrees, my hose. turns on when it it is below 35F roughly, which is fine.

A company that stands behind its product
Style: -20-Degree, Size: 50-Foot
I bought one of these hoses at the end of January and it worked great right off the bat. However, fast forward to beginning of this month and the hose itself had failed, leaking water. I was out of Amazon's warranty window, so reached out to Camco directly for guidance on how to get it replaced.
Fast forward a week and there's a brand new replacement hose delivered right to my door. Easy communication, fast turnaround and no questions asked (granted, the photos I provided were pretty clear as to the issue).
So sure, its not ideal that the first one failed but in a world where it can be difficult to find a reliable brand - I feel very secure working with these guys and they earned my confidence.
Hose works great btw. No issues with the connections leaking, water quality, or temperature. This is the one I'd buy again if/when I have to.

Great idea, but the quality control..
Style: -20-Degree, Size: 25-Foot
*TLDR, Too Long Didn't Read*
Do Not waste your money. Failed right out of box. Leaked at above freezing temps With upstream pressure regulator. Did not test the heating feature due to the hose leaking from under the insulation sleeve somewhere. Very disappointed. Build your own or insulate well. If you do choose to take a gamble with this item then Thoroughly test it as soon as it arrives and take pics/ video. Would share the video but it won't upload correctly, (not too tech savvy), but I know plumbing, mechanical, etc.
The long review:
Other reviews have mentioned the hose leaking or failing Even with pressure regulators (which we use and replace regularly) - this is factual. Failed on first hookup Before it reached the freezing temps.
Please Do Not Buy this sub par constructed item. It's a shame really since we have bought a lot of Camco branded items over the years.
Our unit seemed ok out of the box (bought on sale weeks before the cold season and didn't need it til about 6 days after the return window closed). I should have tested as soon as it arrived but Optimistically Trusted with the 'name brand' mindset.
Amazon was courteous, but did not do anything for us except refer us to Camco to try to get them to replace the defective hose.
Take our hard learned lesson and many others and Do Not buy these products. Either research youtube for making one from scratch yourself or over insulate your water lines/ hoses and set everything to drip during sub freezing temps (mostly applying to full time rvers or camping in colder climates).
We bought the 1in diameter 1/2 in thick 6ft foam pipe insulation (about R2 insul value), foil backed fiberglass pipe insulation (R6 insul value), and then waterproofed with an outer sheath of reflectix and zip ties from lowe's and have had no issues down to 18 degrees with lower wind chills (installed on the fresh water hose, pressure regulator, and water in line filter from spigot post to camper and also wrapped the spigot for good measure). Our rig is 4 season/ belly insulation and sheet metal bottom no skirt.
**Invest in the two way hose splitter off the spigot, add quick disconnects, then a "Freeze Miser" or similar product** It will automatically open and drip before it reaches freezing temps to prevent the water line from freezing.
Easy to unbox, easy to install (like a regular hose), Only After testing for leaking or defects plug into appropriate safe and rated outlet. Not super heavy (25ft). Keeps a semi coiled memory after unboxing but seems to relax and become somewhat flexible. Nice color. Looks quality at first glance (even though several reviewers like us have had defective units).
