The Binefia HF-2 is a cordless water flosser with a 300ml tank, five cleaning modes, a 2,500 mAh battery and an IPX7 rating, and it takes fifth place in this guide at £29.89. The listing carries 4.2 stars from 9,052 ratings — more money than either of the two most-reviewed and cheapest models in the guide, at £19.97 and £24.99, whose rating counts of 47,762 and 29,039 are roughly five and three times as large.

The number that does not close on the Binefia's own page is the tips: the same listing advertises six jet tips and then names five in the box contents. The warranty is stated twice with two different answers, "2 Years Warranty" and "1 Year Worry-Free Protection". The Which? bullet is cut off mid-sentence at "an outstanding 9", so what that figure scores is not stated. Everything on this page comes from the Amazon listing; we have not tested the product.

## Questions people ask

**What is in the box with the Binefia HF-2?**

The listing's Included Components names five tips — two classic jet tips, one orthodontic tip, one periodontal tip and one toothbrush tip — plus the flosser, a USB charging cable, a user manual, a waterproof carrying bag and "1 Year Worry-Free Protection". The special-features line on the same product advertises six jet tips.

The listing says a 2,500 mAh battery takes 3 hours to charge and lasts up to 35 days of use.

**How big is the Binefia HF-2 water tank?**

300 ml. The listing gives no flossing time per fill for that tank.

**Is the Binefia HF-2 waterproof?**

The listing states IPX7 and describes a "dual IPX7 waterproof" design.

**What warranty does the Binefia HF-2 come with?**

The listing answers this twice and differently: the manufacturer warranty description says "2 Years Warranty", while the included components list "1 Year Worry-Free Protection".

**What does the Which? award in the Binefia HF-2 listing say?**

The bullet says the Binefia received Which? Best Buy and Great Value in November 2025 and ranked No. 1 for Cleaning Performance and Battery Life, then the sentence stops at "an outstanding 9" — the listing as given does not say what that figure refers to.
