I've used them all. From the first aluminium Stauns to the latest bronze Stauns as well as the Ferret and now the ARB Ezi deflator. The ARB is by far the best with the built in tyre pressure gauge they are fast and accurate. The Ferret is handy to hang on the key ring and as long as you can count they are reasonably accurate. The Stauns I find are a bit hit and miss. They never deflate to the same pressure twice and as the pressure gets low they become very slow.
