"Initially found it difficult to get a good seal to effect a proper reading. Got there eventually by getting down and close up to the valve. Initially when not getting a good seal the read out reverted to psi which was a pain as I have to use bar units. The tyre depth gauge is a neat extra to have, which was also a handy means of reducing pressure in over inflated tyres. The led light should also prove useful if having to work in the dark. Despite initial probs, I think this is will turn out to be a good purchase in the long run."
"This is a great little tyre pressure and tread depth tester.It starts showing PSI when turned on. (the most usful one-also shows Bar and other strange SI units!) It has a useful swivel end to allow easy access to upside down valves.Nice blue backlight on LCD display and also has a bright little LED that can be used to locate the valve cap after using the tester.. The tread gauge is easy to use also with a clear scale of tread depth. It comes with a semi-rigid case also."
