has anyone got or used these

as above...im looking at getting a couple of gauges but at the moment i cant afford DEFI\'s so these will be good for the time being.

has anyone used these before or have them fitted now?
 
are they any good and do they react quickly to changes in temps in water and oil?
 
Cheers
