TPMS Solar Tyre Pressure Monitoring Systems Color LCD Display 4PCS Waterproof External Sensor Real-time Detection Universal Car Tire Pressure Temperature Auto Security Alarm System

I received the TPMS quickly and it was very easy to fit. It was a matter of removing the valve cap and then fit the locking nut then the TPMS valve cap. Once fitted I went for a drive and pressures reading came through very quickly and it was good to monitor the pressures. The instructions provided is very poor and written in bad English. Luckily I worked out how to do it without it.The only thing that put me off is TPMS valve cap is sealing the tyre pressure and may cause a leak themselves. When new they will be fine, its when they are get a bit older problems may occur. Also, if you need to pump up the tyres, you need the little spanner to unlock the cap before it can be removed. As it is this system works and I am happy with them, just not sure of the long term durability.

I've been using this now for a while and was very happy with it. However a few days ago I got a slow puncture and was unable to get the sensor off the valve, the nut and sensor corroded itself on, in the end the valve broke and I had to fit the spare wheel. When I went to the tyre shop they fitted a new valve and advised to remove the other sensors from the 3 remaining wheels, they were also corroded on so would have meant replacing the valves. I opted to not do this and instead ordered a new kit but with internal sensors, they should be here soon. I'd have given this kit 5 stars had they not corroded themselves onto the valves.TPMS is great, gives great sense of safety knowing that the tyre pressure is correct. If fitting this kit to your car please use oil on the screw thread before fitting and if possible cover the exposed thread to prevent corrosion issues, this might prevent them from welding themselves on. This was the only issue that I had.

Value for money here. Does what it says and it is quite accurate. Also it is solar powered as well. It has been almost a year since i installed it and i have never charged it! In case there is not much sun around you can always recharge it with a micro-usb charger. Instructions might get you a bit confused but dont worry. Just put the correct sensor on each tyre and go for a ride. it will set the basic indications (temp and tyre psi) automaticaly. Then you can play a bit the device a find out how to get the most of it like setting a minimum psi alarm , etc.I would buy again and recommend.hope this helps

This device worked straight away, after fitting the sensors to the tyres. Each sensor was pre-marked with which wheel it was meant so, and each sensor paired immediately with the reader, which is solar powered.I set up the warning levels for both tyre pressure (upper and lower limits) and tyre temperature - again a simple procedure.I didn't want to use the supplied double sided tape to secure the unit to the dashboard, so used some blu-tac, which worked a treat.Being solar-powered, it is constantly charging during the day, but i plugged in to the USB lead when using it at night. All in all, a great buy.

Worked great for little over a year... However locking nuts reacted with the tyre valves and are almost impossible to get off. After 3 days, ordering special release, using acidic cleansers I finally for 3 off. 1 is still stuck on sadly

Receiver is light and has a slightly fragile feeling to it, not that it should be hugely important. It was very easy to set up. As many others have said the instructions are a waste of time, could have been improved with a link to an electronic version at least then it would be more user adaptable to suit different peoples needs needs in terms of poor eyesight etc.Overall I think it is worth the money and seems to be pretty accurate. However the lack of brightness adjustment means I am probably going to return it quickly and see if I can find one that does all the same but includes the ability to actually read it in daylight.**** Update ****Well I ended up keeping the unit and it has been fine although still difficult to read.However, it suddenly stopped working, not display at all. I tried charging it via the micro usb but still not life in it. I went through the Amazon return process and was pleasantly surprised at a very quick response asking me to send a photo or video. I did that and after some confusing messages I thought there was a reason they couldn't replace it so requested some help from Amazon. I was immediately given a gift card to the value.Two or three days later I received a new unit from them so I then had to ask Amazon to refund the refund to them much to the amusement of the young lady assistant on the phone. There was a definite, nice, little giggle as we ended the call. I have since then had another message from the seller saying how pleased they were that I had completed the refund. I have always ended my messages with a Kind regards and the one I got from them today was "Love you". i was a bit surprised. Definitely the nicest thank you I have ever had from a seller.So I now have nothing but praise from them. If you do have to contact them please be prepared for difficult to understand English but understand that they do want to help you,I have changed this to a 5* because of excellent customer service and also an improved display on the new unit.

I didn't expect much from the instructions so I fitted the sender units to the valves before I bothered reading them. The instructions make it sound like you have to do something complicated to pair the senders but in reality it just worked. A quick drive around the corner and they had woken up and were registering pressures just slightly off from my keychain pressure gauge. I don't know which is right but they are within 1 psi of each other. The senders are a bit big and hideous looking but that can't be helped, it's still surprising how much tech they can fit into an oversized valve cap. There's a locking nut that has to be undone with a spanner when you want to remove them so topping up the tyres will be a little bit more involved but not a big problem as long as you keep the spanner in the car.Update: The front left tyre stopped registering after a couple of months. The seller was kind enough to send a new sensor but it didn't solve the issue.
