Autel MaxiScan MS300 Simple, cheap, and very effective..

I've only had this a few weeks, but I've already pulled several codes from my own vehicle (1998 Volvo S70-T5) and a couple coworkers (a 2000 passat, 2005 ram, and a 2006 elantra). The reader is very simple to use and at $30 shipped (a goldbox special) I couldn't be happier. Saves heading over to Autozone just to have them read and clear whenever the occasional code comes on. Two of the four codes I've pulled were due to loose gas caps...one was a loose knock sensor wire, and unfortunately the ram has a transmission computer failure...3/4 of those would have been silly to go to a shop with, but with this reader they were trips that never happened...

Autel MaxiScan MS300 Performs "as advertised"

I ordered this unit for the specific purpose of reading and clearing trouble codes in my 2002 Toyota Sienna minivan. It performs these functions as expected. I've used it twice now to help me understand when it might be time to go to the mechanic. Both times, the trouble code was the same, so now I can take the vehicle into the shop with confidence that something does need to be fixed.

Autel MaxiScan MS300 Works great

Plugged it in, turned on the key, hit the buttons as instructed, and up pops the error code telling me that my TPS is at a low voltage. It cost me $50 for the part and, with my own labor and 30 minutes time, I figure I saved around $100 from having a repair shop do it.

Autel MaxiScan MS300 Perfect

This is the perfect code reader. easy to use and fits nicely in the door pocket or center console. And the price is perfect too. I know many have spent alot more for units that do the exact same thing.
I highly recommend this

Autel MaxiScan MS300 Works perfectly

I needed a code reader because I left my gas cap a little loose after a fill up, and the check engine light came on. My wife had recently had the same issue and had to spend some time getting the code reset on her car. Got the reader, plugged it in, read the code to confirm my suspicions, then cleared the code and my check engine light was out. I now carry it with my emergency gear in the back of the car in case of trouble on a trip. It would be nice to be able to quickly diagnose a check engine light condition and decide if I need to get to a repair shop, or I can continue on and not worry about being stranded because I left the gas cap a little loose. I would recommend this product for anyone who wants to know quickly and inexpensively what that check engine light REALLY means. Easy to use right out of the box.

Autel MaxiScan MS300 At the price I paid.

It was stupid NOT to buy it! This thing has helped me out so much in the past few months. I have a 2000 Chevy Blazer that throws codes like it is its job. Yes, the codes in the manual are generic, but "Cylinder 5 Misfire" is clear enough for me! I agree with the other reviewers that the manual needs some tweaking, but with a little common sense...

If you own a car/truck/SUV that is no longer under warranty and you have even a minimal level of knowledge of car repair, you have to buy this. Helps when you take the car to the garage!
