This device is similar to Maxisys Pro MS908P Automotive Diagnostic Scanner with a few bucks less price. It is compatible to 80 cars of US, EU and Asia. So, if the Maxisys Pro MS908P Automotive Diagnostic Scanner is seem expensive or not suited to your car, then you can consider MS906.

It has an 8.0” LED Multi-Touch display, 802.11b/g/n Wi-Fi to access internet and a efficient battery to run 6 up to hours with no pause.  In addition, it has all the features of MS908P including Maxifix to access to verified fixes and professionals, shop manager to store all the customer details perfectly and many more.

I could not point one single drawback of this miraculous device. The price is also okay considering the advanced features and durability of the device.

4. ANCEL AD310 Classic Enhanced Universal OBD II Scanner

ANCEL AD310 OBD2 Scanners

If you are looking for a simple, basic scanner for your car on a budget of less than 50 bucks, then AD 310 Classic Enhanced Universal OBD II Scanner is the ultimate device for you. This scanner works fast and reads and erases engine error codes effectively. It has a 128 x 64 pixel LCD display and a 2.5 ft long cable to connect with the OBD2 port of your car.

The functions are limited in this device, but we can’t expect miracles from this device within this price. It is useful for checking engine light. We ran different tests with this. It is effective for I/M monitor readiness test, read live data stream, viewing freeze frame data and reading memory, intermittent and historic codes. Showing definition is another handy feature of this device that makes it useful for new users.

Suitable to use a wide range of OBD2 and CAN cars manufactured in US, EU and Asia. But not all OBD2 cars are compatible with this device. So we recommend you to check first before you purchase.

It is a great scanner to use for a beginner. Less complicated operation makes scanning easy for everyone. Besides, AD310 classic scanner is multilingual. You can select the language from a long list of English, German, French, Spanish, Finnish, Dutch, Russian and Portuguese.

It runs on your car power, no need to charge it or put battery in it.The warranty and guarantee I got from this device is longer than the 1000 bucks scanner. I am impressed with the customer service and easy return policy, if it doesn’t work for your car.

The error codes will not be erased unless those problems are manually fixed. This issue annoyed me sometimes. It is not long lasting. If you are lucky, it will work for years for you, if not then it may give up after using 4 or 5 times.

It is only useful to diagnose your engine. Not suitable for ABS scanning. We can not blame it for this tough, the manufacturer claimed it as a engine code reader, not a multi functional device. If you want a multifunctional scanner, than this device is not for you.

Things We Liked

  • Suitable for OBD2 cars of US, EU and Asia;
  • Multilingual;
  • Good warranty and customer service.

Things We Didn’t Like

  • Error can not be erased unless fixed;
  • Its function is limited, only diagnose engine.

5. Launch Creader 6001 OBD2 Scanner Code Reader

Launch Creader 6001 OBD2 Scanner

This code reader cum scanner is a device consists of a 2.8 inch graphic display and a OBD2 cord and a USB cord. It works on vehicles made in US in 1996, EU and Asia during 2001 and onwards.

It has all the features to diagnose any OBD2 vehicle.  The additional features it has are the I/M readiness test, test to check O2 sensor and EVAP system, DTC lookup to clarify and fix the trouble codes and many more! Launch Creader 6001 seemed an affordable, easy to use and perfect to own by a OBD2 vehicle owner.

At first I want to mention the affordability of this product. It does all the diagnosis I require to perform on my car in less than 50 bucks. Other OBD2 scanners may have wide range of advantages but those are out of reach for most people.

The second benefit is its compatibility. It works on any OBD2 vehicles made is USA, EU and Asia. This scanner gets its update from the internet, and the updates are free! Other devices I used had one or two years free update facility on purchase, but for Launch 6001 Creader I never had to worry about updating the software.

I used this to prepare my car for emission test. the I/M test helped me to know whether i should let my go through a emission test or not. This device has seven language setups of English, German, Spanish, French, Portuguese, Russian, and Japanese. This feature makes it convenient to use to other non-English speakers.

The ‘Hot Keys’ allowed me to go to the desired section right away. DTC, ER, I/M and Help are the Hotkeys which makes it less complicated and work faster than other scanners. It is perfect for beginners to diagnose their cars with less complicated device.

It is amazing to find and fix codes, but it is lacking some software to run diagnosis on ABS or Airbag (SRS) systems and some engine and transmission DTCs. It only works on the car when the engine is running. There is no battery in it, so it operates on your car battery. I could not keep it plugged in as i feared to drain my car battery.

The sensor tests are great feature of this device, but it will not work on your car if you are unlucky. Some of the users of this device complained about not working the sensor tests on their OBD2 cars, I never faced that trouble tough. The updating sites are unsafe for computers. My computer security always warned me to connect to those sites.

Things We Liked

  • Affordable;
  • Two years free update;
  • Multilingual;
  • Easy operation;
  • DTC, ER, I/M and ‘Help’ hot koys for convenient diagnosis.

Things We Didn’t Like

  • Limited diagnosis;
  • May not work on all listed cars.

It is lightweight, easy to operate and useful to detect problems and let you know the possible fixes.

The key functions of Actron CP9690 involves reading DTC of engine, ABS and Airbag for a wide range of OBD1, CAN and OBD2 cars of US manufacturers.

The menu is multilingual, you can choose within three languages. The manufacturer Actron claims this device is able to graph, record and playback live data.

The Code connector feature is the most favourite one among all the features of this device. This function lets me link up to their database of 26 million verified and professional fixes of different problems. 

Wide range of compatibility is another advantage of Actron CP9690 scanner. It is suitable for CAN certain OBD1 and most of the OBD2 cars. It mostly covers the US made cars only.

Works efficiently to read DTC of engine, ABS and airbag of the cars. Besides, recording and printing of data is also easy when Actron CP9690 is in your hand. The latest scanners are also capable of resetting oil light and battery, system monitor of battery and alternator charging, dual PID graph and code criterias.

The connector cable is really short, with this I never could work under the hood. Besides, the provider doesn’t supply any USB; you have purchase one to connect it to your computer.

This machine cannot read live data despite of the claiming of the manufacturer. Never heard it read live data among the users.

Limited function is not a problem as the manufacturers claimed it to be limited. Though they incorporated many new and fabulous features in the latest launch of this product, some users also complained about not working some of the features in their car, despite of their cars are listed as compatible to this device.

This device is helpful for DIY lovers and mechanics. It is efficient to detect the problem so that we can realize the depth of the problem and make decision whether it can be fixed at home or needs a mechanic.

The most surprising matter of this device is, it is not compatible with windows devices. You must own a android or apple device to run it.

Another problem we realize is, this device is useless once the Bluetooth starts troubling to connect.  At first it will work fine, but over the time, once the Bluetooth stops working, then it will not work anymore, time to buy another one.

The manufacturer Lemur Vehicle Monitors claims it to be suitable for cars only made in US and EU. Besides, some or all of the features may not work on selected vehicles; such as Volvo, Volkswagen Golf, BMW, Hyundai and so on.

This expense is high regarding to the features it contains. After using for a month I realized, it is mostly useful to read codes of ABS and SRS diagnosis but cannot read codes from other systems. Besides, as per the manufacturer claimed, it is only a scanner, is not capable to command the system for problem solving.
