This is my second purchase of this 12-sensor unit. I sold the first with the motorhome and when I purchased a new motorhome I purchased another. When I purchased the second I did have some issues with the head unit and contacted customer support. We did some troubleshooting and found I had a failed unit. They sent a replacement and all heads were programmed perfectly. I love this unit because it reads not only the tires on the motorhome but also the toad, including the spare. I cannot imagine the horror if I got a flat on my toad and dragged it for miles on the rim. VERY well worth the investment if you pull trailers and want to have the insurance of knowing you are not destroying the toad you cannot see in your mirrors.

Bought the 12 sensor kit and all work as expected. Installed them on a 44 foot 5th wheel camper and was able to get readings without the repeater. About 45-50 feet between camper wheels and display. After 2k miles, I only experienced a couple of brief, single sensor, outages. Nothing to be concerned with. Sensors would come back on and worked flawlessly. The battery in the display unit lasts a very long time as well.

My only complaint is the backlight. It is light activated, meaning the light turns off during the day and there is no way to turn it on other than covering up the light sensors. It's difficult to read without the backlight. Even with the backlight I find it slightly hard to see during the day, but I am old, so that may mean nothing. Regardless, a way to manually turn on the light, and possibly adjust the contrast may be useful. This is the reason for taking 1 star.

I use the Guta tpms in my 38' motor home and tow vehicle. I found it to be easy to install and particularly like the feature of replaceable batteries in the tire sensors. So far, I have not needed to install the range extender, as even the rear tires on the towed vehicle seem to reliably transmit data to the receiver on the dashboard. I purchased the receiver with the single-tire display and it is a bit difficult to tell which tire is being displayed while driving down the road. Fortunately, you don't really have to know because the unit will alarm is anything is amiss. It was a little difficult setting the pressure at which the unit alarms for over-pressure (the instructions were not clear about what value to use for this) so I got false alarms on my first time out because I had set this value too low. Setting the value higher solved this problem.

After 2 years to the date, I had a damaged wheel sensor due to a small crack. I contacted Guta and they replace the sensor with no issues. The system works awesome and would not operate my motorhome and towed without this system. I would highly recommend this product and company to anyone who wants to stay safe on the road

My friend talked me into getting this for my boat trailer to monitor the tires. I tried this out and worked as expected which rotated around to display to the stats on each tire. I also just purchased a 27' camper trailer. As soon as it warms up from the deep freeze we are in now and we can go camping, I can't wait to try on the camper too. I'm hoping I don't need the signal extender for the camper, but if I need to I'll order that. Based on what I've read I'm under the distance and may not need the signal extender.

I definitely want to use while pulling the camper trailer after seeing first hand the damage a blown out tire can cause to the side and underneath of a camper wheel well area. I'm sure a tire monitoring system would have alerted them of an issue about to happen and could have avoided. Now any monitor does not replace good judgment and tires rated for the weight and speed that you need for your hauling experience. The tire monitoring will help me keep the right tire pressure and alert me to issues before they become serious.

One thing to know is don't rely on the YouTube video reviews to know how to use. I was getting stuck and decided to actually read the directions in the included user guide all the way through first and then follow the directions from the beginning. The directions are clear, you just need to take you time to read them, which if hard form some of us. This helps if you happen to start playing around with features and may not be in sync with a video. I will though have to admit the YouTube videos are what helped me decide to purchase.

I like that kits included are extra O-rings in addition to the ones already on the sensors. I'm guessing I'll not need those new O-rings for a couple of years, but nice to know I have them when I need them.

4/3/2021 Update: Over spring break I was able to get our new 27' camper trailer out. I programmed all 4 of the sensors. I hook up the truck and turned the receiver on. After about two rotating scans all sensors were sending reading to the sensor I mounted high up by my rear view mirror. When driving down the road for just about 10 miles I could see the pressure come up gradually about 3 psi just from driving. I did not charge up the receiver since my initial charge and still has a full charge without plugging into the truck's USB. I'm guessing the unit will at least last a full days drive, but if needed I'll plug it in.

I don't plan on leaving the sensors on the tires when in storage. I am making the assumption that the batteries of the sensors will last longer, but not sure.
