What is so good that buyers will "never go back" to rivals?

Revolutionary foam technology

Unlike some standard sponges, the Real Techniques Base Miracle Complexion Sponge is made from revolutionary foam designed to glide product seamlessly onto the skin without leaving streaks or uneven tone.

Being 100 per cent latex-free, the cult beauty buy is soft and gentle, while doing its best work with liquid foundation.

The breathable foam will apply a dewy finish when dampened or a smooth, full coverage when dry.

3-in-1 multi-functional design

Unlike your standard beauty sponges, this unique product comes with three angles, each designed to work with particular facial areas.

The rounded sides target larger areas such as cheeks and your forehead and, when using a dabbing motion, evenly blend most of the product around the face for an even base.

The precision tip covers smaller blemishes, imperfections and the difficult under-eye-area.

The flat edge is used to expertly contour the eyes and nose.

Your whole base makeup routine is done with one little, soft tool which, for most of us beauty babes, is a total win.

All about that precision

We mentioned the precision tip, but it deserves its own heading.

The unique cut combined with the foam technology makes the tip extra sharp, providing a clean application to the most tedious parts of the face, without changing the look of the foundation.

It really is a "Miracle Complexion Sponge" as the tip can dab tiny imperfections, pimples, freckles, you name it.

"Loving how the tip gets into the crevices for under-eye concealer and it works amazingly!," one happy customer wrote.

"I love the double-shaped end so that you have multiple uses for them," another said.

So is the hype real?

Scroll through the nearly 10,000 reviews and you'll find people are buying multiple packs at a time.

"Absolutely love these. Will buy over and over again," a die-hard fan wrote.

"As a sponge, the RT blenders are fluffy and bouncy, and easier to clean than most others," another details.

"The shape is perfect for flipping around to work with the different planes of the face. Blends liquid makeup like a dream."

"I love the shape and the texture is fab too - they don't suck up all your foundation," a third customer reveals.

"I've been using them dampened, with a full-coverage liquid foundation, lightly applied, just patted on, and I'm delighted - makeup goes on really dewy and natural, and lasts all day."
