Review on 🔌 Vesafe Wireless TPMS with 4 External Cap Sensors and 2A Charging via Cigarette Lighter Plug (Color) by Fred Griffin

Update: O-ring failure now allowed moisture (and probably winter road salt) to get into the sensor. The electronics continued to function (but will surely soon be destroyed by corrosion). Most importantly, the corrosion caused the sensor to mechanically fail and all the air in the tire to escape. This error is due to the fact that the internal mounting screw "anchor" crumbled. which "broken" the seal between the electronic pressure sensor and the air in the tire. As I said earlier in this review. Someone (manufacturer) MUST provide a source for replacement sensor o-rings. They appear to be very non-standard (custom) sizes. Otherwise, in my real experience, all sensors will fail. Just don't report pressure. yes, at least let all the air out of our tires! Well, does the manufacturer even pay attention to these ratings? First review: I like this TPMS system mostly (used to be) BUT there doesn't seem to be a source for replacement o-rings that isolate the sensor electronics from the 'elements'. I live in the northern United States (with winter road salt). The original box comes with extra o-rings, but when the sensor's battery dies (after about a year) I've found that all the o-rings disintegrate (lots of cracks and break easily). If the O-rings are broken, the sensors will die from the ingress of water. becomes useless. Replacement sensors cost about $16 each. Some other (external) TPMS sensor brands offer sets of replacement o-rings (of 4) for $4. $1 each. appropriate. We need (affordable) replacement o-rings available from Vesafe (on Revain). If not, I am sure that in a few years all sensors will be destroyed.
