I have used Schwalbe products for years and they used to provide you with a plastic pressure tester included with whichever tube valve type you bought. Quite frankly they were better than this.
It purports to be very accurate (giving readings to one decimal place - this just means that it is wrong 9 out of ten times).
Also and irrespective of the "super accuracy" posit - I tested this against their own givaways (see above) and two other testers (Dunlop and Topeak) and it reads about 5-10 psi low at even some low car tyre pressures (to 1 decimal place of course)
The AV read (with the brass cap removed ) is wobbly and counter intuitive to get a proper seal resulting in lots of hissing and wobbling about and the shrader valve read "jams" on the securing grommet which makes it difficult to remove once a reading has been taken.
At this price point no, not at all, go back to the giveaways or buy a proper one with no accuracy pretentions
Do not store the thing with the adapter fitted - that's what caused all the hissing and wobbling when I first used it - it must deform the rubber grommet for the AV valve reading - but that's how it came to me
Do not over tighten the adapter when fitting it - it will prevent a proper reading.
This is just a BETO product under licence as far as I can see
