With the blend of features and the price point of this unit, you will not find a better deal.  Assuming your looking at these reviews you probably fall in to two main groups.  1.  Someone who is having issues with their vehicle and 2.  Someone who is really into cars or working in automotive towards being a mechanic.  If you fall in the first group and just want to know why the check engine light is on, you can go to a major auto parts chain like Advance or AutoZone and they will tell you why in an attempt to sell you the parts to fix it.  No sense spending money on a scanner if thats all you want. If you want the power of knowing and not have to go out of the way then consider a pocket scan which is cheaper.  For most people you will need to subscribe to Alldata or Chiltons online, or buy a book like Autodata's diagnostic trouble codes to solve some of the problems with your vehicle.  The scanner won't do it for you or put it in laymans terms.  This scanner is more for group 2, this does the i/m readiness test for emmissions as well and is a solid entry level scanner.  If you work in the field I would suggest getting a unit with enhanced obd capability if you can afford it.
