This is what I bought recently and I have found them to be amazing



I now have 2. One for the Bilberry cleaner and one Also for the Megs Tyre Endurance gel

These handles come with a Green Heavy Duty sponge and I use these filled with Bilberry. (£1.33 from Sainburys)
I bought a 3pk of No-scratch White refills (softer) for the tyre gel. (£1.58 from Sainsburys)
You get Great control using these, especially using the tyre shire gel. These seriously are great to use and for the price, they are def worth a try.
One tip is, if u find the no-scratch sponge a little too stiff, just use em for washing up for a week. They will soften up well and will transfer the tyre gel alot easier.
