Car WIFI OBD 2 OBD2 OBDII Code Reader Scan Tool, compatible with IOS, Android & Windows Devices (scanner+gauge)

Sturdy construction, good dial size/resolution. Good seal at valve stem. No detectable leak-down for at least 20 seconds. Accurate best I can tell. Only thing that does not instill confidence is that the minimalist packaging and documentation make it 100% clear this is a direct-from-China product. We'll see how long it lasts.

Doesn't work. New out of the box and the needle wouldn't move. One would think they tested these before they shipped it out. I'm going to try to exchange it. If the next one works I'll re-rate it. As for now, since I'm a military member serving overseas it's going to be a pain since shipping takes 2 weeks each way...

I go to use it once before it was lost or stolen. The fact that it holds the pressure was nice feature. It may not have been 100% accurate, but the reality was it is close enough so you know what your tires are inflated to.

prefer this over the digital read out products which are useless after the battery dies. not sure which is more accurate but i checked this one out against aa gas station pumping machine and it seemed to correlate the readings.

A great item to help you maintain your car tires at the proper fill.It is necessary to check your tire pressure on occasion. this will help you!

Impressive looking quality, however, I'm returning The gauge as it is defective. It registers 45 regardless of the tire pressure. I am going to presume its a one time glitch as I am reordering it.

Not bad, haven't used it much but it's decent. I thought the quality would be a little bit better though.

Works quite easily in all positons. Only had this a short time. Perhaps it deserves 5 stars, but I need it to prove itself for a longer period.
