Equus 3160 well thought out tool

it took a week of going to different sites and reading customer reviews plus time at manufactors home sites there were plenty of negative reviews on many models but on this unit the worst complaint was wanting a larger case. like any tool it takes practice learning how to use all the info available ,The ABS circuit is a plus I own a small used car dealer ship but it has already paid for it self in pointing out driveability issues other brands had reliability issues or customer service issues but so far it is a winner. the hardest part is sometimes finding the defective parts location under the hood I go to my local parts store and they have made use of service manuals for free ( chilton )I like buying from Amazon because of there willingness to work with you if you do have a problem
