Has anyone any experience/opinions of the thermostatic mixer showers sold by 
Screwfix? They have a Pegler Mimo at 99 and an unbranded bar mixer at 59. 
They seem much much cheaper than brands I have heard recommended 
(Hansgrohe,Mira,Aqualever)

What about the ones sold by B&Q (I saw a Tapmate one in store for 79, also 
gainsborough ones are quite cheap) and Wickes (Aqualiss), any good?

Any opinions would be much apppreciated.
