## Questions people ask

**Is it the same as number three?**

Yes: same roller, same price, same pooled ratings, different fields.

14cm across; the 33cm is the length written in the diameter box.

**Why does that matter?**

Because the diameter is the measurement that decides how a roller feels.

**Which listing should I buy?**

Either: both are £13.99 for the same product, so take whichever is in stock.

**Why is it fourth?**

Because the product and price are as good as number three, but the page is wrong about the one number that matters.

**How many ratings does it have?**

6233 at the time of collection, averaging 4.4 stars, with 65 per cent five-star and 4 per cent one-star.
