Review: Solid product (buy extra hose) - Installed it recently, seems to be working well, it came with a very short hose, though, so I had to buy an extra hose in my case to work with Altima 2017.
Review: منتج رهيييب - انصح به بقوه ركبته على التيما ٢٠١٦ وما شاء الله فرق كبير .. بس لازم تشتري قواعد معدنية لتثبيت المبرد و الهوز كان قصير تقدر تدمجه مع القديم وتركبه ( عندي ملاحظة الكرتون يجي الملصق مفتوح بس كل شي كان داخل الكرتون والمنتج غير مستخدم )

### ⭐⭐⭐⭐⭐ Solid product (buy extra hose)
*by S***K on 18 July 2025*

Installed it recently, seems to be working well, it came with a very short hose, though, so I had to buy an extra hose in my case to work with Altima 2017.

### ⭐⭐⭐⭐⭐ منتج رهيييب
*by A***R on 28 May 2024*

انصح به بقوه ركبته على التيما ٢٠١٦ وما شاء الله فرق كبير .. بس لازم تشتري قواعد معدنية لتثبيت المبرد و الهوز كان قصير تقدر تدمجه مع القديم وتركبه ( عندي ملاحظة الكرتون يجي الملصق مفتوح بس كل شي كان داخل الكرتون والمنتج غير مستخدم )

### ⭐⭐⭐⭐⭐ Good quality with good price
*by M***N on 25 April 2022*

It was easy to install in my rav4. And it did what it made for, it reduces the transmission temperature by about 20 degrees. Recommended for crossovers with small cooler like the rav4, it will shift better and hopefully last longer.
