This design is fantastic and I have been put off changing my dated mixer tap for anything else. Whe i discovered this i thought i would give it a try.
The only issue i had was my previous tap was 2 smaller holes on the sink. so i had to drill a bigger hole for this to fit. I purchased some blanking covers to fill the existing holes.
Setup was straightforward and i am very happy with the outcome. I can now put bottles and the kettle under the tap to fill them instead of using a smaller jug first
