Not happy jan purchased tpms10 to do the lap ,car sensors ok with only a few drop outs as far as the van goes forget about it, drops out all the time and 1 or 2 may come back on mainly L/H front and R/H rear, have swapped sensors around reprogrammed all to know avail, have also tried 2 new sensors. Very frustrating when you have alarms going off all the time . Now they are telling me I need to spend another $100 for a repeater. Have just come back from 17000 KLMs trip with 2 other vans, they were both running cheap setup on vans only and only had minor drop outs, whereas my expensive setup did not work the whole time. All vehicles were very similar in length etc. At purchase they don’t tell you you need a repeater as my setup is very similar to most on the road today. Do not purchase in my opinion it is not fit for purpose. Steve
