It's fair. Keep your expectations realistic – U-Scan Review

It's a pocket, on the go, code reader, with basic data stream. Don't expect this thing to do what a several thousand dollar scanner can do. With having owned thousands of dollars worth of scan tools myself, including a Solus Pro, an Encore, Pegisys, SnapOn Brick (MT2500), a Tech 2 and many, many others, this thing works great for "emergency diagnostics". I get to pull ENGINE CODES ONLY at Church, and family/friends houses and other various places. I read another review where the buyer was disappointed it wouldn't read TPMS (Tire Pressure Monitoring Systems). Engine data only. On 1996-newer (including CAN) you can check codes, basic datastream, and I/M monitors (inspection/maintenance) (which is what we use in major cities in Texas for OBDII [1996-newer] state inspection stickers).
