Micro Mechanic Review

The commercial for Micro Mechanic is compelling: It shows a woman who receives a check engine light on her vehicle. She takes it to a mechanic who tells her that her gas cap was loose, then charges her $250 for the info. Had she invested $30 in Micro Mechanic, she could have simply plugged the device into the car’s data port and reviewed the warning on her smartphone app.

All gas-powered vehicles with a model year of 1996 or later will have a data port that can be accessed with Micro Mechanic. To use Micro Mechanic, you simply plug it into the data port and any errors will be described with the smartphone app. While everyone can probably benefit from a device like Micro Mechanic, those who have experienced a series of car problems are probably most likely to want to try this out. Keep in mind that if you are purchasing this for someone who isn’t very tech savvy, you may want to download the free app and sync the device with their smartphone via Bluetooth for them. Once they are synced up, however, it is just a matter of plugging it in, opening the app, and reading the diagnosis.

In the case of benign issues, such as their example of a loose gas cap, this device can pay for itself rather quickly.

I have used several devices like this over the years. The older diagnostic scanners I used had built-in screens, but sometimes the information was presented in a rather cryptic manner. With Micro Mechanic, the results are geared toward non-tech types, giving information in a clear and easy-to-understand manner. Once consumer reviews trickle in, you’ll probably hear of rare instances where no error is detected or difficulties pairing it with the device. Those are to be expected in small numbers for any such diagnostic tool, but they will be among a very small minority of complaints.

Keep in mind that Micro Mechanic appears to be a test marketed product. That means shipping could be quite slow as they often manufacture the product for consumers after initial orders come in. Expect to wait over a month for it to arrive. I’ll update this space if anything changes.


Micro Mechanic looks and functions very similarly to FIXD, a car health monitor now in its second generation. That item has a respectable 4.1 star rating among thousands consumer reviews. This model from BlueDriver is more expensive but yields an even higher rating among over ten thousands reviews.

It was a waste of money when I used it. It just says car is safe to drive. Even when I took the gas cap off. Didn’t warn me about battery or short in one of my spark plug wires after one came loose. Worthless garbage. Also tells me to upgrade for a more detail of problems. It’s a scam and I would never recommend this to anyone

I have tried two micro mechanic adapters in my Chevy Cobalt 2006, good results but when I have plugged them to my Mazda CX-7 2009 they have no worked any more neither again on my Chevy. They don’t appear on my Bluetooth any more.

I am sorry for Charles’s comments about Micro Mechanic, my Toyota Tundra’s light engine went on I put the device in the OBDII and it diagnosed the problem accurate. I even went online and I found exactly the information given by Micro Mechanic. I only paid less than $10 for it. at Ross.

As long as your vehicle has all components functioning in a manner that any faults can be detected early, you shouldn’t have any problems with micromechanic giving you a solution to the problem. Works great and no issues so far! For the price of it at the expense of my son giving it to me after he bought it someplace (AMAZON???) for $20!…couldn’t go wrong. Don’t try and diagnose with it after you have done backyard mechanic stuff, especially electrical wiring, which 90% of the time micromechanic will fail on you. Otherwise trustworthy tool in my opinion after scanning 3… Read more »
