KONNWEI KW310 OBD2 Scanner Full OBDII Functions 10 Modes Car Engine Diagnostic Scanner Tool for All 1996 and Newer Cars (Black)

The product is of excellent quality and as described, Showing Live Data, Reading Codes and Erasing Codes but unfortunately, the (O2 monitor test, Evap Leak Test, review data, On Board mon Test) feature is incompatible with my Chevrolet Optra Magnum 2008 model. It does not work as required, so I couldn’t use it. This may work perfectly for other car models, but it didn’t suit my specific requirements. No complaints about the product itself, just a compatibility issue.

good product , did the job well, instuctions were hard to read too small

The Product quality is poor, it didnt even power on, Product has manufacturing defect and is not compatible with Indian cars, do not purchase it as no replacement and refund is offered. Amazon is selling it as it has a stock of these scanners.

The dreaded SES light came on the other day and my gauges on my vehicle are not working so I was in need of a way to see what the issue is. I have a fancy tablet style scanner from Foxwell but for some reason it wouldn't link to the OBDII protocol of my Mercury Villager last time I tried to use it. I couldn't find it this time around so figured a cheap basic OBD2 reader will do. This reader is pretty basic but does all the functions you would expect from OBD2 standard. You aren't getting advanced features here as those are more geared to the $200+ scanners. This one on sale cost me less than $15 and as you can see from my screenshots, shown me what I need to know. The neat thing is too this scanner has a built in code library so you can manually look up a code and get a description of the issue. I've used the Bluetooth reader from this same company and it's amazing. Mine was stolen so I have to get another but I can't recommend this model KW310 enough if you just need a basic obd2 reader on the cheap!

For the price, this is an OK unit. It does all what it promise to do, can check code, read code, erase code, and show IM readiness status. It is slower than other unit that I have. It takes like 5 to 8 seconds more to load up and connect to the car computer. If you see my attached picture, there is a typo on the error code. It misspelled performance. Hopefully, they will fixed those typos when they put out a new version. Overall, it is an affordable tool that does the job if you don't mind it being a bit slower and having some typos.
