Nice finish. Good quality
This cooler is pretty good quality for the price. Comes with a super long 3/8 hose that fits very snuggly around factory metal line barbs. It comes with a hard line adapter so you can just slip on the hose, and comes with a few worm clamps and zip tie mounts. I personally hate zip tie mounts because there is a huge chance of condenser or radiator damage from the cooler vibrating against it but luckily theres plenty of mounting holes and the inner 4 holes are slightly elongated giving more wiggle room when trying to match up holes to bolt into. The barbs on the cooler are also pretty snug but I still prefer using simple spring clamps to hold the hoses in place versus the worm clamp.. Feels more like it was made to be there rather than an aftermarket addition.

Worked on my CVT Transmission no longer overheats.
Works great on my 09 Nissan maxima. Now I know I am just throwing a bandaid on a bigger problem, but my CVT transmission has 309,000 miles on it. It would heat up and go into low power mode after about two hours of driving in the summer months, since I installed this in series with my radiator, I no longer have any transmission over heating problems. Let’s see how long I can ride this original transmission out now. Oil cooler was easy to install, but you will definitely need to buy an extra line because you only get one length of hose (autozone) and it won’t reach in most applications.

Works fine on 2005 Odyssey
Update 120K miles later: transmission hasn't had any problems. I change the fluid every 45K using Valvoline Maxlife. Cooler may have helped get this far but no way to be sure. Updated to 5 stars from 4 because no problems with cooler and it may have helped. I installed it at 100K to give the transmission longer life (hopefully) along with a fully fluid exchange. Had to install using plastic tabs and in front of condenser because there were no other brackets on the van that I could mount it to and I did not want to take the time to fab up a separate bracket. I also installed an in-line filter with this. Time will tell if this was worth it since I don't do any towing yet so heat has not been a problem yet. Installation was pretty straightforward but you want to go on-line and find the technician diagram for the transmission cooler lines so that you get the correct one the first try. I mounted in series with the stock cooler and after the stock cooler before going through the filter and then to the tranny. No leaks and works fine so far.

Great Buy
Added this to my 2008 Acura TL. I do add these to most of my used cars as it extends the life of any transmission based on the oil running cleaner and less hot. Noticing a difference in shifting a lot smoother and responsive. It was easy to install you will need extra hoses depending how and where you set up the cooler. Looks cool as well if you look closely you can see it behind the grill. Hoping this extends the life on this transmission as it has with my other cars.

2012 Nissan Altima worked out okay
Work okay... a person will have to use you head on how to make it work for their peculiar car..This means mounting it in front of the radiator block.. exactly where to drill holes for mounting brackets ,and will both hoses reach ( barely) and routing them...also the metal hose splice piece was not in the box.. had to buy one.. wasn’t happy about that..otherwise It worked out okay
