I may not be a fair judge of this tool because I own a shop scanner (Snap-On Modis) which I have used for years. I just don't use or need all the features of the shop scanner anymore and wanted to get something a little less bulky and not as much to carry around.The unit comes with a simple quick start guide just like you see every manufacture (except those that give you nothing) supplying today. There is a full PDF manual for download on their site.-A carry pouch that really is nothing special. Should have a separate pocket for the cables and one for the unit but it only has a thin pocket where the quick start guide is located.-A 8' extension cable which should be long enough to reach from a Data Link connector inside the automobile to the work under the hood. Says on the box "OBDII 8' extender cable" but it fits all the Data link connectors.-An OBD2 Data Link connector-GM, Chrysler, Ford and two Toyota (rectangle and round) OBD1 Data Link connectors. No VW so you can't check your old diesels if they would pass emissions.-Cigarette power connector.Takes 4 AAA batteries (not included) but are not required when using a cigarette lighter. They may be good for keeping vehicle information in the memory.I downloaded the software to my PC needed for updating the device and tried to update (came with version 7376 and as of this date software update 8483 is the most current) but waited near 30 minutes for the update which said it would only take a few minutes. How many minutes in a few?!?!?!And for those that complain about not having a cable for updates, Its just a mini USB! I have drawers full of these from devices I have had.I was more in the market for a scan tool that will do OBD1 live data. And since that market is slim for that and the OBD2 market is not, I tested this on my 89 Chevrolet IROC-Z.Entering vehicle information is simple. You don't have look at the VIN and count (Modis asks for the 10th, the 3rd, the 8th....). Year, make, model, engine got me in.You can do engine running or engine off. I tried both. Kept getting a lot of "Link Error" messages as I scrolled down the live data that made me turn the key off for 10 seconds, back on and retry.Now I just did a TPS on my car and adjusted it using the Modis a couple days ago. According to the $7k Modis, the voltage at closed throttle is 0.48volts. This scan tool would not show the volts at that low a range for that particular sensor! It showed 0 volts and did not read until it was opened to one or more volts and rounded showing no decimal. But yet the device is capable for showing volts in tenths and hundredths as I can see by looking at the MAP readings. So that takes away the convenience of not having to use a volt meter and back probing.I was about to unplug something to set a code and see how this works on that, but at this point I was already disappointed and wanted to pack it up.Get rid of the data link errors and the lack of proper, fine voltage readings and this may be a very good and useful tool for a person that an OBD2 or OBD1 vehicle (says for 82- 95 OBD1 yet I know here in California that OBD1 computer controlled vehicles started appearing in 79(80MY)) The paper clip to activate the flashing Check Engine light works well. But to be able to watch the data helps to confirm the issue (maybe even show multiple codes as being one culprit). That helps to save money by not throwing parts at a vehicle.
