Why would you buy this here for 300 when you can buy the same thing directly from the manufacturer for 200

MAJOR GAS SAVER

Customer Rating:
Bought the KIWI and started using it in my 2004 Toyota Camry. I travel via 2-lane highway about 180 miles each way almost every weekend. This goes through about 6-8 small towns and is not freeway driving by any means. I used to get 34 mpg highway. After using the Kiwi, mileage gradually increased to 38 mpg. They recommended switching to synthetic oil and my new "record" is 41.6 mpg. This is a very good product. It also analyzes the check engine light for you when it comes on so you can decide to get it fixed now or wait. It basically teaches you how to drive to save gas.

Did not work

Customer Rating:
Unfortunately, I read nothing but glowing reviews of the Kiwi, but it didn't glow for me. In fact it didn't turn on. We called Kiwi customer service and they were nice enough saying to just send it back. I bought this item new but the rep said somehow we must have gotten an older model? Needless to say I am not happy since this was a christmas present for my husband. I might be a littler happier if my money was refunded but I'm still waiting. I trust Amazon and have rarely had a problem. I hope this doesn't turn into one.

Gas Saver

When you plug this thing in you are greeted by a beautiful bright screen. The user interface is pretty easy to navigate with the directional keys. Text is large and straight forward.

Once the unit is plugged into your dash's OBD II port it scans all that information into the device in real time. I drive a WRX so this unit plugs underneath your driver steering column. Once the unit is powered it figures out your vehicle's performance. It knows how much you accelerate and brake, then the unit some how figures out a mathematical formula to teach you how to drive more smoother.

Before getting my unit I was driving about 21MPG. Driving using the Kiwi's tool I was able to push it up to 26MPG. My WRX isn't very efficient. So your mileage may vary.

A Great Tool for Daily Commuting

Customer Rating:
I've had my Kiwi for several months now and I'm very pleased with it. It's been a fun, neat and valuable tool for me to experiment with my gas mileage during my boring commutes to and from work. My daily commute ranges between 20-30 minutes and I've been using my Kiwi to determine which route saves me the most time and gas. With the Kiwi I've discovered that my driving behavior plays a tremendous part in my fuel efficiency. I've also been able to discover which routes save the most gas.

I've experimented with my driving behavior quite a bit and I've noticed that my Lexus can range as much as 35% on the same route. On some days I'll drive aggressively by accelerating rapidly and braking aggressively. My Kiwi Score would drop to about 78 with an MPG of about 20 and a cost per trip of ~$1.4. On other days, I'll baby the car, keep my momentum in turns, plan ahead and stop gradually and I'll get a 92 Kiwi Score with 28 MPG and a cost per trip of ~$1. When I arrive at my destination, the Kiwi will show me a trip summary with all that information, which is a nice feature. I've also noticed that there's a definite correlation between my driving behavior score and my actual MPG.

Before I had the Kiwi, every morning I'm always caught with a dilemma. Should I take the longer freeway route or should I take the shorter city route to work? With the Kiwi I've discovered that my city route to work is 9.0 miles where my freeway route is 12.2 miles. I've also been able to discover that my longer freeway route actually saves more gas and time than my shorter city route if there's no freeway traffic. I check the traffic with my iphone every morning now and if there's no traffic, I'll take the freeway, and if there is, I'll take the city.

The engine check feature has also been useful. A buddy of mine drives a BMW M roadster and forgot to screw his gas cap on tightly. Apparently BMW has a pressure sensor which checks for this and throws an error code on the dash. I look my Kiwi out and reset his light for him saving him at least $100 from having to go to the dealer.

All in all, I'm happy with the Kiwi. It does what it's advertised to do and requires no maintenance. The unit is easy to install, turns on automatically and turn off automatically.
