Ive had an email from these people who have advised me its free shipping to the UK for a set of 4

 

I am very tempted.....but......at $110....about £77 theyre very cheap.....

that cheap they make me wary....

 

what do people think?

They are crap. First thing I did to the car was to turn that off after 1 month. A proper calibrated hand gauge used every week is much better and more interesting to use.

 

 

If I could pry them off my wheels without damaging them you could have them for free!

????  :huh: In what way do you find them crap?  Accuracy or what?  I have 2 sets, one on each set of rims and very accurate in direct comparison to a calibrated motorsport grade hand held.  The point surely is they detect a slow puncture before you get too far on and either damage tyre or worse.

I got the Saab ones mentioned earlier in this post on my 2nd set of wheels. Works great and as Al. mentioned gives a warning if something is slowely developing. For track days I use a hand gauge though.

I found them crap for a couple of reasons that eventually I found out were common experiences with others who tried them on various track cars - with temp changes the pressure number constantly changes and becomes a meaningless number on the dash and several times set off low pressure warning when nothing remiss was actually happening. 

And the sensors seldom calibrate correctly - when the tires were all even (checked with my calibrated guage) often the number on the dash was different for some wheels. So gave up trusting it and then what is it - pointless weight to counter balance on the wheels with wheel weights.  

 

I did not get them mounted on my second set of wheels. And when the time comes to refurb my set which has them they will be removed.

 

Bottom line is I don't trust them and its a common experience.
