4 Tire Inflation Deflation System, 4 Tire Air Up Down System, 4 Tire Pressure Equalizer, Inflate or Deflate All 4 Tires at Once, Flexible Air Hose Fits Up to 155" Wheelbase.

Worked great for letting down and airing up my tires for off-road use. Made it all quick and painless.

I was going to knock off one star for the listing describing the hose as Hybrid but decided not too. It's a std Air line hose that's made of a pvc/plastic coating. It's not a true hybrid where it won't kink or is flexible enough where it lays down flat without curling. I did not have any leaks (did a leak down on the lines/manifold and the pressure loss was <10psi over a 10hr period) when I tested indoors. But one of the quick connects did leak if wiggled when used outdoors in a colder environment. Otherwise the hose and manifold works as intended. One note was that the seller was very responsive when I reached out to discuss the hose quality. That said, I added a star back but left one off because of the slightly odd configuration of the hose lengths and the questionable longevity of the fittings. On that note, the lead hose to the first tire is longer than usual which should have been added to lengthen the wheel base portion instead of having to stretch between tires. It was O.K. for my truck application but I can see where this could be a problem with some longer wheelbased vehicles. I was initially annoyed by this but it ended up working to my advantage when I aired up the tires on my boat trailer. That extra length helped reach both rear tires from behind the boat and the wheel base distance did not matter so much on a dual axle trailer. Overall, good quality and a responsive seller.

Works absolutely good almost better than most of my friends which have big brand names

Easy to use. Very good quality.

Works as advertised But the bag it comes in is garbage. Used it for the first time yesterday when I for a drive in the mountains. Aired down to 20 pounds using the kit, worked great. At the end of the day used it again to air back up to 30 pounds. Rolled up all the hoses and put back in the supplied bag as I was zipping it up the bag came apart.I'm hoping that it isn't a sign of things to come with this kit.

The product quality is very good, and the shipping was fast! Like all products time will tell ultimately how good a product is or the customer service will be if needed. The extended 2 year warranty is great if I have any issues down the road.

SUMMARY3.5-stars -- Acceptable product; convenient equal pressure for 4 tiresBACKGROUNDThis came up as a Vine suggestion. I've been meaning to build myself one of these for my Jeep, but never seemed to get around to it. So, when Vine offered me one up for review, I figured it was worth it.INITIAL OBSERVATIONSManufacturing quality seems acceptable. I did not notice any obvious defects during the initial examination of the product.COMPLAINTS / ISSUESI would have preferred to have had small globe valves at each tire chuck so that I could independently turn on or off the flow of air to each tire, but it appears to be using standard 1/4" NPT fittings on the hose ends, so I can add that myself once I get motivated enough to do it. :)It would have also been nice if it had provisions for a 5th tire for those of us who have a spare tire mounted on the rear of our vehicles and who use it in our tire rotation pattern.IMPRESSIONSI'm not sure this actually decreases the total time that it would take to air up all of your tires, but it definitely makes it easier to have the same pressure in all the tires and it allows you to do it without constantly stopping and checking pressure to see if you are at the target pressure. So, instead of actively holding the tire chunk on the valve stem and checking pressure, you can hook everything up, sit back, and enjoy a beer while everything is automatically balanced. The digital pressure gauge is easy enough to read that you won't even need to put down your beer while checking it. :)CONCLUSIONThe product seems acceptable and it appears to meet all the specs in the ad. The digital pressure gauge seem like it is made by the same company that I received with a different tire chuck package and I have had no complaints about it. As such, it rates "slightly above average" (i.e. 3.5-stars).ORIGINAL AD DESCRIPTION4 Tire Inflation Deflation System, 4 Tire Air Up Down System, 4 Tire Pressure Equalizer, Inflate or Deflate All 4 Tires at Once, Flexible Air Hose Fits Up to 155" Wheelbase.$129.99STAR RATING SCALE5.0 Excellent product (or perhaps customer service); There is NO room for improvement whatsoever; NOTHING is perfect, so this rating *should* be EXTREMELY difficult to achieve.4.5 Very above average4.0 Above average product; Something about it sets it a bit above similar products on the market.3.5 Slightly above average3.0 Average product; Meets expectations, perfectly serviceable, but does not do anything that sets it apart from similar products; Does not have some features that makes me say, "Wow, that's a neat feature".2.5 Slightly below average2.0 Below average product; Something about it is a bit lacking; It could be conflicted specifications or errors in the original listing or that it was arrived with damage that was unlikely to have occurred during shipping and should have been caught in either the manufacturer's or seller's quality control.1.5 Very below average / slightly poor1.0 Poor product; Waste of money at ANY price; Blatant lies in the original listing.0.0 Extremely poor product; doesn't work and seller either ignores contact attempts or takes an extremely long time to respond, possibly trying to run out the window for returning a product; possible scam seller; a seller or product has to screw up *really* bad to get this score:ORDERED:2024-11-02:RECEIVED:2024-11-05:REVIEWED:2024-01-23:ASIN:B0DDK8M3CVLast Modified: 2025-01-23 20:35:21
