Have used this system for two years and quite happy at full price - Very well engineered, works very well. Battery life round 1-1.5 years.

With a few tools like a Jack and a few bricks it would not take long for someone to nick all 4 wheels! Or with a tennis ball steal the whole car. How far do you wanna take it?

I would not do without mine now, it is a must have accessory, real time monitoring and audible warning if tyre pressure goes above or below 2 psi, that you set.

I don't know about app versions but I bbought a dedicated version on Ali express for around £45.
Mine is solar powered display with separate charger socket. You can have bar or psi, audible warning. Simple to set up and fit, as its wireless.
The valve caps are large, but not a problem. They come preset with LF and LR, etc so they are on the correct wheel.

You put a lock nut on the valve stem first, then screw on the valve cap, then back screw to the valve cap and it locks in place.
Unless you have the special sized spanner to unscrew the locknut, they cannot be nicked.

Who checks tyre pressures?

Screwing these on sounds like introducing something that could itself blow/leak thereby letting all air out of the tyres. Are they well enough engineered to be safe?

I am waiting for the "wipe my backside" devices . . . don't know if an app will be needed?

Picked mine up today. It was a nightmare to set up. Only two of the caps seemed to connect and you had to start again everytime. Useless. Being returned tomorrow.

I will buy this for my grannie who is half paralised on a wheelchair..christmas present sorted.

Not a fan of phone apps since they always want access to your personal data when they have no need for it.

I have used Tyrepal for around 5 years to guard very effectively against flat tyres. At around £150 per tyre, these systems pay for themselves with one puncture, let alone the many benefits of having correctly inflated tyres

Thanks OP. Ordered for pick up. Great Deal. Wanted these for a long time for my caravan, but always too expensive. :thumbsup:

Someone would nick these from the tyres. My metal caps got nicked when the car was parked... (i can hear the questions coming... Where did you park? :)))

Good luck on this one, I put some chrome valve caps on my car and someone nicked the lot. :angry:

Thanks OP

Seem to be various others on Amazon, similar or better for the £40 mark, e.g.

Voted hot. Same price on Maplin's amazon page:

Have bought to put on my wife’s car, she is a nightmare for driving on under-inflated tyres. I would think this is a cracking idea for trailers and caravans too, this is plus £100 everywhere else too :raised_hand:

Ordered after a few pints on a Saturday night. Mrs not to happy.

How large are these caps. The one review on maplin isnt clear. If each cap holds a Cr2032 battery they must be massive?

Check whether the threads on the inside of the caps are plastic or metal. I used low tech pressure sensors from amazon (green/yellow/red caps depending on pressure). Those stuck on the stems and would not budge due to rust in just a couple of months and i had to pay to have the stems replaced at a tyre place.

Great. Thanks

You are right .. Hot deal ..10 minutes to set up and warns of low pressure. I find a cheap pressure gauge and inflators a good ide
