AQUALONADouble Tap Bath Sink Shower Head Hose Spray Hairdresser Pet Push On (Double Tap Fitting Duet 1.3m In Length)

I need a shower for my kitchen sink, the taps a smaller than bath taps. Will this product work on Sink Taps?

can you move the spray head around, or is it fixed? & have old round taps just under 2cm,measured underneath where water comes out would this fit?

Would this work on outdoor taps? I have a hot and cold tap but want a mixer to hose the dog. Thanks.
