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

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 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.

Original feedback 2019 4 star : Gave 4 stars overall as this lacks a simple feature, the ability to disable audio as I only want visual feedback. ( audio gets annoying ).Updated 2021 1 star : reduced to 1 star as the pressure sensors that attach to each tyre valve had corroded and siezed up so bad I had to cut them off using a rotatory tool.

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.

I picked this device from the a variety on sale - but I am pleased that I chose this one! Easy to install . . for each tyre a small tyre pressure device is installed in place of the dust cap. Within less than a minute the small dash device (I chose to rest it on the dashboard) starts to show the current tyre pressure of each wheel.For the next couple of days, all seemed well and I got into the habit of checking the tyre pressure by glancing at the displayed pressure at the start of a new trip.However, after 3 days of 'all looks good' I noticed at the start of the trip that one of the tyres was showing 2 pounds pressure lower at the start of the run. I thought that this may have been due to one side of the car being in the shade. However, as I was just about to turn onto the motorway, I glanced at the pressure monitor and saw that it had lost another 2 pounds so I turned round and went home, dropping into my local garage and asked them to take a look.The garage tested all my tyres and found that one of them had a large nail in it! The garage replaced the tyre it for me and advised (and showed me!) me the issue that has occurred and that this could have been quite dangerous if it had failed at speed.Great safety option at a great price!
