Typically a mixer that does not swivel can be purchased on the cheaper side with an ok life expectancy.
Swivel style mixers however can come loose very quickly, and end up with leaks where the movement is made or have issues with cheap fixing systems. Because of these issue it is highly recommended to install only quality tapware with brands such as Linsol, Methven, Caroma, Grohe, HansGrohe and so on.
We often look for products that have a ten year+ labour and parts warranty as well as a pressure rating of at least 800Kpa. If not, it may require the instaltion of a pressure limiter at your water meter effecting the whole home
