### ⭐⭐⭐⭐⭐ ecellent spare for kitchen mixer tap
*by D***S on 26 August 2025*

excellent spare and company will not go any where else in the future cost reasonable but good for the price .this spare fits a hotpoint kitchen mixer tap

### ⭐⭐⭐⭐⭐ Works fine
*by A***R on 21 December 2025*

All ok and as ordered

### ⭐⭐⭐⭐ Decent cartridges, but does NOT fit Blanco taps
*by J***S on 11 March 2024*

These are reasonable quality tap cartridges. The look like fair value for money, but they were not suitable for my tap so I had to return them. The item description needs more detailed dimensions to be provided. I bought these hoping they would fit my Blanco kitchen tap. The Blanco has 28 spline cartridges, and by the two other dimensions given in the description (e.g. 53mm tall) it looked like they might be suitable replacements. As they are cheaper than official Blanco replacements I thought I would give them a try. However when I came to fit I found two problems: 1) the spindle has a wide 'shoulder' just below the splines and these prevented the tap handle from fitting properly 2) the splines diameter is a little smaller than the original part meaning the handle would wobble a little
