Hose ruptured at 80psi, rated at 200psi

The compressor is fantastic, the the tools it comes with are sub par. My air hose ruptured after 3 uses at 80psi. It is rated to 200psi, and it made it nowhere close. The rest of the attachments are mediocre.

I would caution that you use care when replacing. May get damaged if the hose is too tight and you use excessive force

I was disappointed with the quality of the hose - not as strong as expected for "Heavy Duty CONTRACTOR GRADE".

I think the hose would be fine, but the first time it was used it leaked in two places.  I need to get a replacement or something.

I changed the setting while it was turned on and under pressure (50psi according to my testing). Now it leaks under the yellow part. Not tons, but more than it should. It's also not very heavy and I have to make sure the hose doesn't make it sit at an angle. Patterns work well enough for what I use it for.

Already burst after only owning it for two months.  The thought of these hoses are cool, and I wanted to buy one to see if I liked it, and upon first hooking it up, I was impressed, but after only two months it ruptured, so I do question the strength as I have had the same rubber garden hose for over 10 years and it's still doing great, it was the same price as well.

The hose burst after less than 1 month of use under household water pressure.  I have two other NeverKink Max hoses (black with a grey line) that
 I purchased at a home center and they have held up well for more than one year and the price was about the same. Other people have reported bursts with this hose which is black with a red line.  The "commercial" designation does not really matter.  I do not recommend it.

Something inside the hose has deteriorated as it has sprung a leak halfway down the hose.

The first time this hose was unrolled and used, I found that it had a leak at about the middle of the 100 foot section of hose. This is not acceptable for a new unused hose. I hope seller stands behind the product with a replacement.

It has 1/2" NPT tank port for air inlet from compressor which is 1/2" copper line that seems adequate for a unit with this CFM...and I intend to use it with 1/2" x 100 ft air hose with 3/8" quick connects.  However, the other two tank ports are only 1/4" NPT, like for a wimpy electric compressor.  One is used for gage, which is OK.  The other small tank port becomes the discharge that feeds tool...so they used a wimpy 1/4" regulator along with similar pipe fittings, and a 1/4" hose quick connect.  I know someone will tell you that the pressure drop of these small fittings/regulator is "not significant"...but, hey, I bought this big unit because I wanted the most air possible...not just "adequate".  This also becomes a mechanical problem...the small fittings look fragile, and note that they are the only connection between your 200 lb workmen and your 200 lb compressor.  In my opinion, 1/2" NPT outlet fittings should have been used for more air, and more strength!

The hose arrived kinked (it is supposedly kink-resistant). It was a rather low quality hose, but what surprised me was what happened when I went to attach it. I bought the hose to connect the outside hose bib to my hose reel; when I went to attach it to the reel, the (male) brass fitting simply pulled out of the hose! It was never properly attached, I could easily insert and remove the brass fitting from the hose; this made the hose completely useless. Fortunately, Amazon makes returns so easy, UPS arrived at my front door the next day with a shipping label in hand, they picked up my box and back it went! I can't tell you where to find a better replacement for this hose. What I did was buy a new hose longer than what I needed, I cut off a 12-foot piece, and fixed the ends with a brass 5/8-inch hose repair kit. I wouldn't have needed to buy a new hose, except that my current hose (which was a very good hose, but longer than I needed) was 3/4-inch, and I could not find a decent repair kit for a 3/4-inch hose.

If you have a similar need (for a short hose to attach to a hose reel) and decide to cut up a longer hose, here's a tip I used: Cut the (longer) hose at the end where it attaches to the hose reel. That way the (sharp!) hose clamps for the hose repair kit stay near the hose reel. Otherwise you will have a hose clamp on the end of the hose that you hold, certain to cut and jab you repeatedly.

The clear bowl has cracked on the bottom under 80 psi..  Caught it dripping before it flooded my finished basement.

Very high expense for a hose which has very poor quality female and male connections.  The hose is excellent in construction and does what it says in operation.  Previous reviews said the fittings were a problem and it happened within a week .  They came off and could not be reattached.  I would have reordered, and I know Amazon would have covered it, but it is easily fixable with quality connections and clamps.  Had to purchase both brass connections with clamps from Lowe's to correct the situation.

I used this hose lightly since I purchased this in March 2015. Watering the yard and the hose popped two holes around the middle of the house. I attempted the refund route but Amazon indicates this is not longer eligible. A hose this expensive should not give-out so soon. A 1-star is too high and DO NOT RECOMMEND anyone buy this hose. And do not buy it from thru Amazon.

DON'T use the supplied rubber hose 90, as it will split around the clamps, leak and cause floor damage.  Noisy, but working 1 year later still.

The hose itself worked nice for about 6 months. I have a faucet in my garage so the hose was kept indoors. It burst a couple of weeks ago with minimal use. I'd say this product is good when it works and definitely saves space however the workmanship seems to be poor.

I connected the hose to the faucet, unrolled it (good non-kink action) and gave a slight tug. The ring that connects the hose to the faucet came unattached from the hose.  I had bought the hose assuming that anything sold at Costco is of good quality, and was disappointed when I saw the ratings in the reviews.  I am disappointed in Costco that they are providing a product that does not get primarily 5 and 4 stars in its ratings.
