Rated 3 out of 5 by Pembo6 Not good Have been using this for a while now. Great price from CRC. I added this to my basket so I would get up to the $99 required for free postage to Australia. Seems accurate but a bit cheap build quality. Hasn't stood the test if time. Rubber worn out so it doesn't seal properly. I wouldn't buy another one. Lasted about 6 months with infrequent use. Fit well in the camelbak. 28 June 2014
Superb quality item very easy to use, bought as one of my M bikes has 90 deg valves so old one wouldnt fit this one does as just push on. On my other bikes with vertical valves this doesnt fit as not enough room, will be fine for cars so beware if buying for m bikes.
I have used this type with different vehicles over several years, they are pretty accurate and reliable. You do have to keep them square on to the valve but this isn't difficult. The only downside is that the rubber seal will eventually perish and you'll have to replace the unit, but having said that they are the best small type I have come across in my 34 years driving.
