ZEEPIN TPMS Wireless Tire Pressure Monitoring System with 4 DIY Sensors, Real-time Displays 4 Tires' Pressure and Temperature TPMS (External TPMS4)

Worked great until the summer heat hit. The dash unit is designed to sit on the dash in full sun so it charges via solar. I live in Phoenix AZ and leave the car outside all day. Once the daily temperature got to 100 the display started to flake out then once the temp hit 110 the unit failed completely. I suspect it would be fine in any other climate.

I got this a couple weeks ago, I have to admit I was a bit skeptical of the item due to the low price. Installation was painlessly simple by just putting them onto the valve stems finger tight, then using the included tool to secure them a bit more.My truck has TPMS already installed on it, however I was looking to use this for my 21' dual axle travel trailer. To test the usability of the sensors and unit I installed the caps on my trailer, within 30 seconds the display was reflecting the PSI of the tire and the temperature of the tire. I was impressed with that information. Once they were installed I started to take a little walk to check the distance that it would reach, I took the display and walked away about 20' and waited a few mins and had no issues. I moved about 10' each time and didn't find any loss of signal till around 70-80' or so which is more distance than it is from my wheels to the front of my truck none the less the cab of my truck.Having a solar powered display is awesome, you don't need to run any cables to power it. It's also great that it can be charged with USB in the event that you run this at night with limited to no light. It didn't come with a USB cord but I have plenty laying around. I used a USB port to give it the full initial charge before dropping it in my truck for using it, this way I insured that the unit was fully charged when I started using it.Time will tell to the long term durability of the unit, but to be honest the cost of the kit is less than buying 4 sensor's that go inside your tires on your vehicle. I'm buying a couple more of these kits for my mom and dad who don't have TPMS on their vehicles.

This little purchase gave me SO much peace of mind on our recent family trip with our new travel trailer. A tire blowout on a travel trailer can destroy the trailer and cause a terrible accident, so I was scared out of my mind about that happening to my family. Our trailer dealer said that we have to keep a close eye on our trailer tires and recommended a TPMS. I got on Amazon and found this - a little skeptical at first because it was solar and I wasn't sure if the distance from the unit to my trailer tires would work, but it works like charm. Just to be sure, we checked the tire pressure with a gauge after every few fillups and the tire gauge read almost exactly what the TPMS display said, within 1 PSI give or take. This is the one product I recommend to other people on the RV forums. By the way, there's NO getting these off without the little tool it comes with, so don't lose that!

The recommended max tire pressure on my travel trailer tires is 80 PS I.I usually run them at 72 to 75psi. cold.The maximum you can set psi on this unit is 74 psi before the alarm goes off, so the alarm is constantly on if your tire pressure ever goes over 74 psi.In the picture the readout is still on and the alarm still ringing even though the trailer is parked 15 miles away. That was the last reading before I parked the trailer.Maybe the unit is defective. The alarm does go off for several minutes if you push one of the buttons on the top of the unit or leave it motionless for a period of time. A great idea for wireless monitoring and safety if it worked properly. Unfortunately the trailer was in storage and I didn’t check these out until it was too late to return them to Amazon.These only work for me if I silence the alarm every time it comes on by pushing a button. That is a real nuisance.I don’t know if they have any kind of a warranty.

The media could not be loaded.  Airstream Travel trailer user. Higher PSI version is the Favoto Brand which we ended up with. Favoto can sense up to 87PSI (Zeepin alarms at 73lbs max which alerts constantly in warmer weather as tires can increase 10lbs more in warm weather towing. and better the this version. Selected external sensors (non-feed through) for a late model 25ft Airstream travel trailer. Slow, fast leakor blowouts and potential tire damage to the aluminum wheel wells or surrounds can go unnoticed until too late costing many thousands. Needed to find something to monitor the tires but seeing the 300.00-450.00 for name brand versions, but didn't like their displays much.Read an earlier good review using this for a travel trailer. Due to such low cost ($50.00) thought it was going to be a toy or not perform but either way could test and return if needed. For theft concerns, figured in 1 minute total we can quickly replace the original stem caps once arriving to a destinationReceived in 2 days (Prime) in new condition. Charged, installed and ran a load of tests for hours and WOW ! UNBELIEVABLY FANTASTIC..5-1lb PSI accuracy to a digital meter, <1 second alert of pressure drop and high low temp and pressure threshold settings. Amazing long range tested to 100+ ft in free air. Solar and Micro USB direct charge port with long battery life. Overall, crazy incredible buy and value even if it was 2x price. Would test on your own travel trailer due to verify signal strength and range. VERY Impressed and telling our Airstream buddies needing TPMS about it.

This TPMS does not come with charger and charge cable. The seller said it powered by solar. I only used this TPMS for only half hour, it is out of battery. How does it be solar charged at night time or not sunny days? Brand new product, only 4 sensors, there is one sensor defective. I used it for only 2 days, now second sensor malfunction, can you believe that? I have equipment to very precisely charged to 29.0 psi for each tire, it is accuracy to 0.1 psi. The three sensor reading is from 20 psi to 50 psi, could be any random numbers, never has the correct reading, The plastic edge is very sharp, not smooth, it can cut my skin. Also the plastic wrench and accessories, etc., all poor quality. Very poor made product. The LCD display was defective two weeks later.

So funcionou por uns 4 dias ai 2 sensores pararam de funcionar

Legal para monitorar mas não achei tão preciso! Mas ajuda!
