TymateTire Pressure Monitoring System for RV Trailer - Solar Charge, 5 Alarm Modes, Auto Backlight & Sleep & Awake Mode, Tire Position Exchange, with 6 External Tmps Sensor (0-87 psi) and A Repeater

Pros: 1. Main unit/repeater and the sensors seem well built and I didn't have a problem installing those components. I have a 23 foot trailer and the main unit is at least 16 feet away from the sensors and the connection with the repeater works great. 2. The unit seems to work accurately but you need to be moving to get updated readings but there are many caveats and frustrations( discussed later). 3. The solar charger and manual plug in for the master unit works great and really nice. 4. The semi-sticky dash pad is nice and a must to keep this thing in line of site 5. The main unit LCD screen has plenty of size and could be far far easier to useCons: (I really need this thing but frequently tempted to throw it out the window at times) 1. You better keep the manual close by at all times because the interface and operations are NOT intuitive at all. You need to sit in detail with the manual and set up your thresholds for alarms on temp, pressure and adjusting scales of measurements aka (Farenheit vs Celcius and PSI vs Bar). 2. Once set it seems to work but it also chirps and beeps at times that i don't understand making it very annoying sometimes to know if something is truly wrong or its just beeping for a temporary condition... So i tend to just cancel the alerts and just keep it in line of site and check it from time to time. 3. You don't get real pressure readouts until you're tires are moving by design(Which the seller even emailed me about so you don't think its not working once installed).... And if you do get a readout while idle or just starting it up, it may be the last one the unit remembered and not a current reading which is another confusing point (Its not clear sometimes if it is showing a previous reading vs a current reading) I think it has to do with the sensor design and maximizing battery life... I think it uses tire rotation to actually engage the battery for operations and when the tires are stopped the sensors are unpowered halting the needless continuous transmission to the main unit. 4. Because you must be moving to get a reading you cannot take a pressure reading before you pullout on a trip unless you uninstall and reinstall the sensors which is a bit of a pain (keep your little tools close by as well as its not just twisting them off it has a lock nut). Otherwise you would have to drive get a reading, and if its low pull over and then put air in the tires on the road (Aka not desirable)... Would be VERY nice if you could tap the once sensor while stationary just to get a current pressure reading to the main unit. 5. It comes with dust caps for the sensors but there is absolutely squat about them in the manual as to when/if we should use them and the proper way to put them on... the install instructions says zilch about them. 6. If you are not using all the sensors like i am(single axle) its even more confusing... as there doesn't seem to be a way to inform the unit you are only using 2 of the 4 sensors So this makes the already cumbersome interface difficult to read and perhaps that is why it chirps sometimes because it chirps out of the blue when in "alert" mode... 7. I've accidentally long hit a button and it went into a "weird mode that had unreadable characters on it" and i finally got back after hitting another button a long time and playing with it.** The functionality of this even if partial and frustrating is worth it to me still... if i'm driving long distance and i occasionally see the PSI fluctuate a couple pounds due to getting warmer or colder i know its working and doing its them and i know what the temp readings are which is the basic safety features i'm really after... I think the UI could be 50 times easier than it is. I would be ok with the 1x tedious setup but the status display needs entirely redone along with how and what the unit alerts about is not intuitive...How about something VERY simple like flashing simple messages from a small library of phrases every few seconds like this1. Last read 3 seconds ago2. PSI: FR 65, FL 64, RR NA, RL NA3. Temp(F): FR 80, FL 82, RR NA, RL NA4. Alert PSI: FR 595. Alert Temp(F): RR 1806. Monitoring Paused/Disabled* And that's it... super simple

Easy to setup and use. Great product. Works likes a dream and the extender is nice to have.

I don't like when someone buys something and immediately reviews the item having not actually tried it. The way it shows up at your doorstep does not say anything for how the item will actually perform.I Purchased the system with six tire monitors about three years ago for my 36 foot bumper pull camper. I have since been on over 4900 miles of travel with this same system.For starters, I mounted the transmitter on the front of my camper and wired it to the camper battery. Because there is no simple on off switch I installed a battery disconnect switch so that the transmitter wouldn't drain my batteries in the off-season.After all of the hours of use and miles driven I can report that this item has worked flawlessly for me. At no point have I had any glitches or sensor issues. I've been through rain, snow, high temps, low temps and several very bumpy gravel roads. I have not had one singular issue with the sensors. I was originally concerned that the distance between the sensors, transmitter and receiver was too far with my camper. But, I've had zero issues with connectivity for transmitting due to the distance between.The only issue I have encountered was that I overtightened the sensor with the backing nut when I tried to remove it it twisted my valve stem. That is more my fault than anything. Easy fix with a little patience.When I encounter long periods of non-use, I always disassemble the sensors and place back in the original packaging for storage. This also includes the monitor for the cab. The system has operated very nicely and would purchase again.

I wanted a TPMS system for my new travel trailer. If you've ever had a blowout in a trailer and did not know it until you heard metal grinding you'll know why. This unit is much cheaper than some of the more mainstream brands so I thought I'd give it a shot.I've only used this once, but here are my impressions. It's cheap and it appears to work (with some qualifications). The manufacturer recommended I get the unit with the range extender. I did get it, but tried it out without the repeater. It did sort of work, but I had to move the display around on my dashboard to get all 4 tires to read out. And to me this uncovered one of the things I do not like about this unit (possibly the same problem other brands have). This unit will give you a readout whether or not it is actually receiving live data from the sensors. When I started driving, I saw 3 of my tire pressures and temperatures increase, but not my rear tire on the driver's side. It just read the original numbers. when I picked the display up and moved it to the left of the dashboard, it began giving live info. The problem is, unless you're paying attention you could be loosing tire pressure and not know it because there is no "live pulses" function that tells you you're getting live data. Another thing I don't like about these kind of screw on sensors (and I think this applies to even the more expensive brands) is that you must basically defeat the Schrader valve in your tire when you screw the sensor in and hope the sensor does not leak from an internal defect or loosen up and leak (they supply lock nuts that are supposed to keep this from happening). Its a bit of a pain to put the sensors on, and if you ever need to add air to your tires you have to remove the sensor and then re tighten it and put soapy water on the valve to make sure its not leaking.The display is small and can be hard to read, but not that bad. You charge the display unit using a USB connector and it has a solar cell on top that is supposed to keep it charged while you are driving. I've only used it for one short trip, so I have no idea how effective the solar charger is. I assume if this is a problem you can just plug a USB connector into the unit on your dashboard.There is a high/low pressure alarm setting you can put in the unit. My tires are supposed to be 65 psi cold, so I set the low to 50 psi and the high to 70. The pressure in one tire reached 71 psi and the alarm went off immediately. So I think this unit will do the job as long as you insure you're getting live data. Its nice to get in the car and be able to make sure you've got proper tire pressure without having to measure them with a gauge first.

Except for the size of the screen is why my 4* rating. Very easy to set up. I am using it on our 44’ Toy Hauler.
