GT20 TPMS with 12 Sensors and GB30 Repeater

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.

Great product. And the rechargeable battery worked for our entire 4,600 mile trip without recharging.

The product is not difficult to install and programs quickly. The pressure and temperature are fairly accurate. I did accidentally hide my trailer tires on the display and couldn't figure out what the problem was. I contacted Guta customer service and they responded quickly. I figured out the problem by re-reading the user manual carefully and although customer service didn't solve the problem, I do appreciate their timely response and efforts.

I invested in this TMPS in advance of a trip we will be taking in January. Having worked in the tire industry for a number of years I understand the importance of both air pressure and heat on tire failure and therefore being able to have this information communicated to be while driving is extremely importantI must say, the included instructions were a bit hard for me to follow. I did find a great You Tube video that explained the process. There are only two buttons to enter into the programming mode but the duration of how long you press them offers different programming features. Once I had that down, programming was a snap.The unit worked effectively on the couple of short trips that I have taken since installing and I expect it to continue to work for our longer upcoming trip. I will certainly amend my review in not.The only real issue I had was the quality of the stickers used for the sensors to identify the wheel positions. They did not stick as it appears the glue had evaporated or dried out. I used a Dyno label maker to create my own tire sensor ID's.I installed these on a 37' Class A and do not need the repeater. I plan on installing 4 more sensors for the toad and am glad the sensor came included with the purchase of the TMPS, in the event it is required to read the sensors on the toad.Happy and Safe travels to all
