Product works exactly as described. The hardest part was digging the hole for the sensor.Doesn't work but 5% of time below 40⁰, only works at 25 % of timeAnother update- dropped back to 3 stars. This accessory seemed to be working but unfortunately has stopped again. The longest it has worked is about a week. Then it must be recalibrated. When it fails, it opens the gate. So I have woken up on many mornings to find the gate opened in the middle of the night.Update: changed from 4 to 5 stars. Item works great now. I removed dirt around sensor. Buried it just a bit deeper and now it works every time.Original post: The first one I ordered would not calibrate. Customer service sent out a new one right away. Excellent customer service. The second one is working great now but I have had some issues with it. Hopefully, that is resolved now as this is really a great feature for when you have guests. If you are not worriedabout guests you can simply use your car remote to exit. Overall, Ghost Controls is a great company with excellent product and a very easy to use manual.Received one wand and it immediately opened the gate with no metal present. Turned the power on/off at the gate box then unhooked the white wire - still did not work.Per Ghostcontrol tech support here is how to recalibrate this wand:Good Afternoon, I'm Dalton from Ghost Controls technical support team. I read the description you gave and it does seem to be a problem with the vehicle sensor, I'd like you to try a full re-calibration at this time. Remove both the vehicle sensors RED and WHITE wires from the control board. Wait approximately 15 minutes, to allow any residual power to drain, then reattach the WHITE wire only. Wait an additional ~15 minutes then reattach the RED wire. This will trigger a full re-calibration of the wand. Ensure that during this process there are no vehicles or any other metal objects in the vicinity of the sensor, as well as the placement of the sensor is approximately 20 feet from the fence and buried 10-12 inches into the ground. If this does not solve your issue please let me know by responding to this email so I can contact you for further troubleshooting.So: Email Ghostcontrol.com if you have issues - they give excellent customer support for their products.I really like this device it is very responsive and I’ve had no failures in the last four months that I’ve installedFriggin Excellent. I initially bought the wired gate opener, but I could not make it work... even after a call to Ghost support. But once I installed this, it synched up with my control box and has worked like a charm for the past month. I recommend burying a small metal post or pieces of rebar to support the transmitter, but otherwise, this was great right out of the box. ***if your gate opens unexpectedly, ants may have gotten into the battery compartment- i used borax to get them out and everything works great todayThis Ghost Controls AXWV Wireless Vehicle Sensor for Ghost Controls Gate Opener Systems is one of the best i installed it 6 months ago and love it works perfectly with no issues would recommend easy to install, i also installed one for a friend and should have got a Commission for the sale from Ghost but didn'tThis was very easy to install But it was constantly opening the gate! We tried recalibrating it two three times a day while we had it! When it let the dogs out that was it I had to send it back! No technical support from GC!
